摘要：

岩溶库区渗漏及坝基渗漏勘察往往需要投入大量人力财力和技术。给出了岩溶库区与坝基地下水渗漏勘察的3个实例，对典型岩溶库区渗漏进行的示踪试验表明，渗漏主要受库岸岩溶发育程度控制，水库蓄水水位剧烈变动成为诱发渗漏的主导因素，随着库区水位平稳及河流泥沙对库岸溶洞的淤填，渗漏会随之减弱。典型水库砂砾石坝基渗漏示踪试验显示，渗漏具有主渗通道。示踪成果为水库防渗加固治理提供重要依据。大型示踪试验是一项复杂的勘察工程，把握示踪试验过程与质量监控是取得成功的关键。

Abstract:

The investigation of karst reservoir area and dam foundation seepage often requires a great deal of manpower and considerable financial resources as well as techniques. Three examples for such investigation have been demonstrated in this paper. The results of tracing tests show that seepage is mainly controlled by the degree of karst development in reservoir adjacent areas, the intense fluctuation of reservoir water level is the main factor triggering the seepage. The seepage will weaken with the placidity of reservoir water level and filling of silt in the cavities. The results of tracing tests for sandy gravel dam foundation seepage indicate that the main seepage passages exist. Tracer test results can provide the basis for reservoir reinforce and seepage prevention. The large-scale tracing test is a complex investigation work, in which the key is to pay attention to entire tracing process and quality control.
