摘要
为了解杨树岭隧道区岩溶水系统发育特征,预测隧道开挖过程中的突水地质灾害,通过野外工程地质、水文地质调查,从地层岩性、地质构造等角度研究岩溶形成和发展规律,分析岩溶地下水的补给、径流、排泄途径,归纳总结岩溶发育规律及岩溶储水类型。在此基础上,结合断层、褶皱等地质构造的分布规律以及物探成果等,初步划分可能发生突水、涌水等地质灾害的危险地段。研究结果可为该隧道设计、施工方案的选择提供依据和参考。
In order to find out karst water system development characteristics of the tunnel area and predict water inrush geological disasters during the tunneling,through field engineering geology and hydrogeology survey,formation and devel-opment pattern of karst is studied from the points of lithology,geological structure,etc. The recharge,runoff and discharge of karst underground water is analyzed,and the development law of karst and karst water storage type is summarized. Based on above,the hazardous location that water inrush and gushing water may be occur is preliminarily divided,accord-ing to the distribution of fault and fold,and the geophysical results. The results can provide basis and reference for the tunnel design and construction scheme selection.
