Discuss A Number Of Engineering And Technical Problems Influenced On Mountainous Freeway Cost

Since the big development of the western, the highway construction of our country, especially the mountainous area highway construction has obtained the considerable development, the construction scale and investment scale is increasing. Because of its inherent characteristics, Mountainous area highway construction projects, of which the huge amount of investment for the development of national economy, have become the focus of attention. Western mountainous area highway construction is developing rapidly in such an environment, the traffic mileage ranks first in the country. At the same time, there are also many problems, such as design of construction organization in the lack of or incomplete cause leakage or less accrued expenses, ignored costs vary greatly between different bridges when bridge scheme was selected, different wall rock classification caused of different index of cost, the main material price fluctuations affect the mountainous expressway and the "super three" phenomenon,, and so on. In order to make the project to achieve the perfect combination of technology and economy, of which must being faced up and solved in the construction process of the project. Thesis of "influence of mountainous highway cost by a number of engineering and technical problems" as the discussion, the main contents include as below:(1) Study on the engineering and technical factors of mountainous expressway cost,includs the cost personnel experience, design phase of construction measures and cost comparison, rough calculation and budget, preliminary design of bridge scheme design stage economical comparison, influence of wall rock classification of tunnel construction cost, intercommunication construction interference problem, effects of the key factors of the earliest road construction cost and the diversity of investment main body of previous engineering cost and the impact of Investment channels of previous engineering cost.(2) Technical measures and engineering cost of expressway in mountain area. Based on the statistical data of main material price fluctuations on expressway construction project in Chongqing area, in statistics the main material price fluctuations Influence on the freeway cost indexes, further analysis the technical specification and standard impact on highway construction cost.(3) Study on the essentials investigation and method of highway engineering cost in Mountainous area. Highway engineering cost general contents of verification and the reflection of "super three" problem, audit objective and the content of audit, and give a detailed description through examples.
