How to keep healthy development of city, overcome and the breakthrough restricts the bottleneck that the city develops, become the government must pay attention to and solve the problem. This paper aimed at Changchun North Lake Bridge construction project, by using the theories and methods of project management, project from the project to project optimization design selection, projects from the social and economic analysis to the risk management analysis, proved the project construction is scientific, rationality, necessity, for the region to accelerate a city to change a course, drive a city development, raise a city to build a level to provide reliable basis.In this paper, in order to Changchun North Lake Bridge project as a background, elaborated project project construction necessity and significance. Changchun city infrastructure especially traffic network is relatively weak, and the city the momentum of rapid development is serious lag and disconnection. Construction of North Lake Bridge, is the establishment of center city needs, is to implement the construction of city space needs, is the realistic need of traffic growth, is to improve the road network system is needed, Changchun Regional Logistics development needs, is the development of metro, enhance the land value needs. Changchun North Lake Bridge construction, to promote regional economic development strategy so as to drive the long northeast core area of rapid development, at the same time, alleviate effectively because of the economic development led to the development of the logistics industry on the road network pressure, to sophisticated infrastructure planning and construction as a fortified city bearing capacity and the service function, these are put forward the construction of this project and the fundamental reason why.In bridge engineering design scheme needs to be considered in the use function, technical, economic, aesthetic and social aspects of the effect of integrated argumentation, put forward several feasible scheme, and the scheme selection. According to Changchun North Lake Bridge project construction condition and overall planning and other related requirements, through the use of fixed base prediction method of exponential curve model of Changchun City traffic is analyzed and forecasted, the road function and scale evaluation, determine the minimum according to main road 8 Lane two-way road design. On this basis, from the functional requirements, structural safety and feasibility, practicability of construction and landscape, environmental protection and other aspects of the overall design train of thought. Determine the comprehensive design, pay attention to environmental protection, prospective and moderate scale balance, short and long term consideration of four principles. In bridge scheme selection, this article from the bridge, the landscape effect, technical difficulty, difficulty of construction, economic cost and time aspects, using the city bridge project risk assessment theory, of the three solutions for a comprehensive comparison and selection, determines the final scheme. Finally, according to the national and local relevant norm of the final solution, are briefly discussed in the investment estimation, on the North Lake Bridge project financing source and financing options for a simple, clear the project capital and loan capital from reliable sources, repayment guarantee, project capital gold and debt financing scale is reasonable, lower financing costs, the smaller risk, financing is feasible.In order to Changchun North Lake Bridge project as the breakthrough point, briefly introduced the project management and project evaluation, the project management and project evaluation concept and significance. From the project environmental impact assessment to proceed to Lake Bridge project, the possible impact on the environment analysis, forecasting, put forward to deal with the adverse effects and the countermeasures. From the construction period and operation period the possible sources of pollution, put forward the optimized design scheme, green vegetation, strengthen construction management and strengthen the operational management Mitigation Project on environment influence countermeasure. Then it introduces the social management the purpose of the evaluation, characteristic and task, using project evaluation theory, the North Lake Bridge Project on social impact analysis. North Lake Bridge project construction and implementation of the Changchun City Economic and social development will produce bigger positive effect, greatly promote the local development of various undertakings. After the completion of the project, municipal infrastructure, public facilities will continue to improve, improve land utilization, improving the living environment. The project with the Changchun City social, cultural, environmental and so on has the good compatibility, by various interest groups welcome, will promote the Changchun City region economy fast forward. Finally introduced the project management of national economy evaluation of the content, function and basic principle, apply national economy evaluation theory of Changchun, North Lake Bridge Engineering made the economic cost benefit analysis, the North Lake Bridge project construction significance, improved the Changchun City and surrounding areas of transport conditions, to improve the regional economic, social and natural environment Changchun City and surrounding areas, improve the people's living standard.City bridge from the evaluation angle, elaborated project project management project risk concept, content and steps of project risk management, project risk analysis of the content and the main method. According to the theory of project management, introduced the basic procedure of project risk management, risk identification, risk prediction in turn, risk evaluation and risk response measures. From the identification, evaluation, decision making, decision making, implementation countermeasure inspection five aspects, discusses the North Lake Bridge in the process of risk management, and proposes the risk avoidance, loss of control, risk retention and transfer risk four risk coping strategies. Finally, according to the Changchun North Lake Bridge project's basic characteristics, the use of project management risk analysis theory, the proof of the project investment risk. The main bag political policy risk, financial risk, management risk, cost risk, market risk, social risk and environmental risk, through the fuzzy analytic hierarchy process, comprehensive Changchun North Lake Bridge investment risk probability and risk level, according to the risk assessment matrix (omitted ), clear lake bridge investment risk. Secondly, from the construction risk and the durability of the two areas of risk, comprehensive Changchun North Lake Bridge Durability of risk probability and risk loss grade, on the basis of the risk assessment matrix (omitted ), clear lake bridge durability risk.Through the use of project management, project evaluation and project risk analysis theory, the Changchun North Lake Bridge Engineering Project Design and management of comprehensive evaluation, draw the following conclusions:The construction of the project can not only improve the Changchun city overall network traffic structure, alleviate urban traffic pressure, meet within the region of the rapid growth of traffic, and can expand the city space, promote city development, accelerate a city to change a course, raise a city to build a level, further optimize the Changchun city ecological environment, promote the rapid development of the surrounding area.The engineering project engineering materials rich, building a good condition, raise money in capital raised by local bank loans and two kinds of ways, conform to the actual financial situation of Changchun city. The project investment scale is larger, design, construction cycle is short, must strengthen project design, construction organization and management, control the design, construction drawing design work, seize the key link of the construction engineering project, strengthen project management, organization and coordination, actively with the railway, land, planning and other departments to communicate, and management perfect the relevant departments of the approval procedures, and shall be in accordance with the construction schedule in financing and reasonable arrangement, ensure engineering construction on schedule, ensure the smooth development of the project.
