摘　　要：作者在现场工程地质勘察、试验基础上，对我国西南某大型水电枢纽坝基所遇特殊的复杂埋藏型岩溶、承压水问题进行了研究，弄清了坝基岩溶、承压水形成条件及发育特性，对坝址选择及工程处理的决策具有重要意义。ased on the field investigations and from results of chemical experiments, the authors studied the complicated buried karst and deep underground confined water, clarified the formation conditions of karst and underground confined water beneath a dam foundation, and divided the underground water system into two parts: the first one is an underground water system in cracks or karst; the other is underground confined water system. Then it is pointed out that there is no hydraulic relation between the two systems. These results will be beneficial to selection of dam sites and engineering construction.
