摘要
Abstract
Due to the complex geological conditions of the area where high-risk tunnels pass through, the construction easily encounters unfavorable geological bodies, such as faults, folds, high geostress, karst aquifers, etc., which would cause geological disasters such as instability of surrounding rock , water gushing, rock burst,etc.Therefore, it is very important to find out unfavorable geological bodies and take support measures to ensure the construction safety before excavation.Because of the complex geological conditions and unfavorable geological bodies in the construction area, Daqinling Tunnel of Xi'an-Chengdu PDL (Passenger Dedicated Line), as one of the difficult and key sections in the whole line, is classified as a high-risk tunnel.In order to make sure that the tunnel construction smoothly passes through the unfavorable geological bodies, in the advance geological forecast,the integrated techniques of geological logging and geophysical prospecting(TSP and GPR) are adopted, and the unfavorable geological bodies are successfully forecasted , which provide effective guidance for tunnel construction.关键词
