Comprehensive Survey and Research on Expressway in Mined out Areas
The number of expressway construction projects in China is increasing rapidly in recent years.Geological survey is the first step in the implementation of expressway construction.Mine goaf geological survey is a key factor in the successful implementation.This study area has complex geological conditions along the route.The expressway passes through a mountainous area,which is a kind of large-section mining area rarely seen in China.The special adverse geological phenomenon in the mining zone has an adverse impact on expressway design and construction.In this paper,comprehensive geological survey methods are proposed based on this project.
