摘　　要：岩溶地区水库渗漏是碳酸盐岩地区兴建水利枢纽的主要工程地质问题之一,尤其是在可溶岩广布、岩溶发育强烈、地形复杂地区。拟建兴文县新坝水库地处岩溶地区,存在岩溶渗漏的可能性。通过对该水库库区地质概况、岩溶水系统进行分析研究,论证了水库潜在的三条岩溶渗漏途径均不会发生渗漏;并利用库区降雨量与泉流量进行水均衡计算,计算结果进一步论证了该水库不存在岩溶渗漏问题。Water leakage from a reservoir in the Karat region is one of the main engineering geological problems in building hydro project in carbonate rock regions, especially where with resoluble rock widespread, developed Karat and complicated topography. There is possibility of water leakage in reservoirs in the karat region. This paper expatiates general geology and the Karat water system in the reservoir region, then demonstrates that in the Xinba reservoir there is no problem of water leakage. Moreover, this paper makes water balance computation by rainfall and spring discharge in reservoir region, and the result makes sure that the reservoir has no problem of water leakage too.
