摘要
龙开口水电站工程枢纽区地震基本烈度为Ⅷ度,基岩场地设计水平峰值加速度为0.394 g,大坝抗震分析和抗震措施设计是工程关键技术问题之一。采用数值计算方法和模型试验,对碾压混凝土大坝进行了全面的动力分析,并根据研究成果进行了有针对性的抗震设计。
The basic earthquake intensity of area where the hydraulic structures of Longkaikou Hydropower station located is 8 degree, and the peak value of horizontal acceleration in rock base area is 0.394 g. The seismic analysis and design is a key engineering problem for Longkaikou project. A comprehensive dynamic analysis is conducted for the RCC dam by numerical methods and model tests, and the specific seismic design is carried out according to these researches. earthquake resistance; design; measures; Longkaikou Hydropower Station
