摘　　要：水库大坝建成后,有利于库水中有机质的富集,坝址周边环境发生剧变,致使下层库水弱酸性和含侵蚀CO2在向坝基运移过程中,与坝基岩石、帷幕、混凝土间产生物理化学作用,导致化学侵蚀作用。本文将根据近年来对水口电站坝址环境水监测结果,分析其水质特征及侵蚀作用并提出应采取的防治措施。After the Dam for the Reservoir is completed , great changes in the environment around the dam site will take place. The environment changes furthermore result in the changes of water quality in the reservoir , and the rock of dam foundation , curtain and other concrete structures under the water are easily eroded by physical and chemical action of water. In this paper , the author analyzed the characteristic of water quality and erosion action , and put forward some countermeasures of prevention and control to be taken , based on the test results of environment water around the dam site of Shuikou Power Station in the past few years.
