四川紫坪铺水库区水文地质与工程地质条件研究

分析了四川紫坪铺水库坝区和库区的水文地质和工程地质条件。由于库区内基岩山区为强烈上升区，地形切割深，高差大，各种不良工程地质现象发育，虽然不致于影响水库的正常工作，但也应引起充分注意。水库畜水后，渗漏问题对水库区和坝区影响较大，应采取相应措施解决；水库蓄水后，库水有可能下渗，应加强对该水库诱发地震的监测和研究。

Hydro-geologic and engineering-geologic conditions of Zipingpureservoir area,Sichuan

This paper analyzes the hydro-geologic and engineering-geologic conditions of Zipingpu reservoir area,Sichuan.It has been found that various types of harmful factors exist in the reservoir area where the bedrock around this dam have been strongly uplifted and large difference of topographic elevation have been produced due to deep down-cutting.These factors are unlikely to affect the normal working of this reservoir,but must be fully noticed.After water being stored in this reservoir,problems from the seepage or leakage of water will significantly influence on the area of both the reservoir and the dam,and should be resolved by adopting some steps.The water seeping into the underground following the water storing may induce earthquakes.So the work of monitoring and investigating the reservoir-inducing earthquake should be enhanced.
