Overall Design And Application Study Of Mountain Area Expressway

Design is the soul of the project, the design will affect the final results of the project. The expressway projects design is the overall General Plan of the construction of the Expressway Project, requires coordination between the professional internal and external relations, to ensure standard, scale, program, to form a complete system engineering, to achieve security, environmental protection, and the overall objective of sustainable development.Because of the unique topography, geology, hydrology, ecology and other issues of Mountain Expressway, the project was technically complex, large scale and high cost. Due to many different professional characteristics involved in the specific professional engineering, and even deviates from it, it is difficult to coordinate between the various professional focus.By analyzing the characteristics of mountain expressway, summed up the general design principles of Mountain Expressway, from the overall line, interchange overpass, foundation engineering, bridge engineering, tunnel engineering, construction costs and other professional aspects should take priority of their characteristics are described in detail on the profession itself in the overall design are discussed.In the paper, through application of engineering practice and the specific route described indicators of the overall use of the flat vertical experience, get the corresponding index value; elaborate to grasp the main points of the structures and balance the overall selection process, statistical structures of multiple projects related to cost index used to measure the overall cost structures and the rational layout and guide how to grasp the overall design of indicators point.
