摘　　要：柬埔寨甘再、达岱水电站是地处柬埔寨王国西南部的2座水电站,工程区同属热带雨林气候,地表水属低矿化度水和软水,水中HCO3-含量绝大多数小于0.7 mmol/L,属中等强度溶出型侵蚀水质。文章以试验为基础,分析了软水侵蚀的机理,提出了具有针对性的工程处理措施,可供同类地缘属性的水电工程参考。The Kamchay and Tatay hydropower projects are located in the south-west part of Cambodia.Both project areas are in tropical climate and the surface water belongs to low-salinity water and soft water,in which the contents of HCO-3 are mostly less than 0.7 mmol/L,belonging to moderate dissolution type erosive water.This paper analyzes the mechanism of soft water attack based on tests,and proposes specific engineering counter measures,which can be referred to for hydropower projects with similar geographical attributes.
