引漾入洱——桃园水库岩溶渗漏浅析

Analysis of Karst Leakage of Taoyuan Reservoir in Yang Water to Er River Project

通过对桃园水库地层岩性、地质构造、水文地质条件及岩溶的论述,基本确立水库及坝址区岩溶发育规律及地下水排泄方式、方向,排除水库库区存在岩溶渗漏,坝址区岩溶发育随深度增加而减弱,防渗帷幕基本成立,基本论证了水库成立的可能性,为下步工作提供较可靠的工程地质成果依据。

This paper confirms the karst regularity and the type and direction of ground water discharge both in reservoir and dam site by discussing the characteristics of Taoyuan Reservoir,such as stratum and lithology,geologic structure,hydrogeological conditions and karst,and that there is no probability of karst leakage in the reservoir.The karst development is becoming weaker along with the increasing of the depth,so the impervious curtain is available.This will provide a reliable engineering geological data for next work.
