摘 要:冬奥会山区综合管廊1^(#)支洞区域地质背景复杂,为了科学地指导1^(#)支洞路由选址工作,通过地质测绘、钻探、工程物探、原位测试、水文试验、室内试验的综合勘察技术方法对综合管廊1^(#)支洞的主要工程地质问题进行了深入研究与分析。结果研究表明,断层带破碎、突水涌水、围岩稳定为1^(#)支洞突出的工程地质问题。在此基础上,确定了综合管廊1^(#)支洞地质选线原则,并结合建筑信息模型(building information modeling,BIM)三维模型,对北线、南线方案进行了比选,确定了地质条件相对较优的南线方案。研究方法可为存在类似工程地质条件或工程地质问题的山区地下工程的地质选线提供一定的参考与借鉴。The geological background of the No.1 branch tunnel of the mountainous area integrated pipe gallery of the Winter Olympic Games is complex.In order to scientifically guide the routing and location selection of the No.1 branch tunnel,the main engineering geological problems of the No.1 branch tunnel of the integrated pipe gallery were analyzed through the comprehensive survey technology methods of geological mapping,drilling,engineering geophysical prospecting,in-situ test,hydrological test and indoor test.The research show that the fracture of fault zone,water inrush and water gushing,and the stability of surrounding rock are prominent engineering geological problems of No.1 branch tunnel.On this basis,the geological route selection principle of No.1 branch tunnel of utility tunnel was determined.Combined with building information modeling(BIM)three-dimensional model,the schemes of north line and south line were compared,and the south line scheme with relatively better geological conditions was determined.This study can provide some reference for the underground engineering in mountainous areas with similar engineering geological conditions or problems.
