Comparison and Analysis of the Program of Constructing Road at Crossing Lake
Comparison and Analysis of the Program of Constructing Road at Crossing Lake
At present, there are two methods to construct road at crossing lake in the city: the first method is filling lake and constructing road, the second one is building bridge cross lake. The method of filling lake is simple and low cost; The method of building bridge is difficult and relatively high cost of construction. How to determine which program should be used? Based on an example of constructing a main road in a certain city, this article analyzes the problems after the completion of the construction with the first method, such as the pollution to the environment even though the cost is low, the destruction of the natural landscape, water erosion and scouring to the roadbed, roadbed settlement and road damage under full vehicle load pressure, high frequency and high cost of maintenance and conservation, and its influence on traffic safety and so forth. Although the method of building bridge has high one-time investment cost, but it can increase the effective use of road performance, extend road life, reduce maintenance costs, and improve the natural landscape. With the Comparative analysis of the examples, from the aesthetic and technical point of view, revealed the planning and principles to be followed in dealing with the above mentioned problems accordingly, also provides a useful reference for the design and construction units in dealing with the similar issues.
