Comparison Research of the Geological Conditions of Huayingshan Super-long Tunnel Schemes on Guang'an-Linshui Highway
Guang'an-Linshui Highway is an important high-grade road connecting Guang'an City and Linshui County.The engineering geological conditions and hydrogeological conditions of Huayingshan Tunnel,the dominant engineering,are extremely complex,and the construction and operation risks are extremely high.To reduces the construction and operation risks of tunnel engineering,this paper analyze the engineering geological conditions of the tunnel site area,with a focus on two major engineering geological issues:karst and karst water,and coal mine goaf.According to comparison of geological conditions under different schemes,the tunnel scheme with short karst development section,small karst water hazard,small impact on the environment,and short length of coal mine goaf is determined.
