The Analysis and Solvement of some Geotechnical Topics in Post-Disaster Reconstruction Highway

Abstract:

Article Preview

The highway in earthquake region suffered serious damage during Wenchuan’s Earthquake in 2008. In all projects of post-disaster reconstruction, the reconstruction of highway and making highway work once again are prerequisite. There are a plenty of rock fall, dangerous rock, landslide, and debris flow sections along the highway between epicenter areas Wenchuan County to Li County. Among the post-disaster reconstruction of the highway, efficiently solvement of these disaster or potential disaster is one of geotechnical engineering topics. Phyllite rock occurs in large number along the highway but is defective fillings. This kind of material if not made full used, it will be able to lead to filling shortage and environmental disruption. How to treat it as a resource for roadbed fillings is the second of the important geotechnical engineering topics in the highway reconstruction. There are many narrow sections along the highway, and Inside Mountain is not stable. Common anti-skating retaining wall is not fit the severe condition because of its basement dug being harmful for mountain slope steady. How to pass this kind of sections is also bottle neck technique. The above technical problems are analyzed and the relevant solutions are proposed. So the troubles are solved efficiently and the highway is open to traffic on schedule. The terms of settlement provide reference for similar highway reconstruction projects.
