Application of high-density resistivity method in investigation of mountainous highway tunnel

摘要

With the rapid development of China's highway construction extending to the mountainous areas, highway construction is faced with more and more tunnel projects. How to identify the geological structure, lithology, bad geological phenomenon and other geologic factors of the mountainous tunnel site is of importance for design and construction of tunnel projects. This paper takes the New Pine Ridge Tunnel Project in State Road 108 as an example, highdensity resistivity method and traditional exploration technologies were adopted in the proposed tunnel site to solve the tunnel investigation difficulties in complex mountainous areas.
