摘　　要：拉西瓦拱坝是建在高寒、较高海拔地区的250 m高薄拱坝,坝身布置有表、深、底孔泄水孔口,坝体结构受力复杂。安全监测设计主要根据坝址区工程条件和结构设计成果,遵循相关规范和经验选择监测部位和监测项目,设计中考虑了施工期、蓄水过程和永久运行各阶段的需要,提出了系统的安全监测设计方案,并在拉西瓦拱坝施工期和初期运行阶段发挥了重要作用。The double-curvature arch dam of Laxiwa Hydropower Station is 250 m high which is built in a cold, higher altitude area. The stress status of dam body is very complicated because of the layout of surface, deep and bottom outlets in dam body. Dam monitoring positions and items are selected according to engineering condition of dam site and structural design of dam, and in compliance with relative specification and experience. After considering the requirements of construction term, impounding process and permanent operation, dam monitoring system is designed and has played an important role during construction and initial operation period.
