摘　　要：针对黑河龙首二级水电站发电厂房基础为活断层且断层破碎带宽度较大、又地处强震区等问题,根据现行规范要求,采用ANSYS构建了厂房基础的三维有限元静动力模型,获得了厂房基础各工况的抗震计算结果,论证了厂房基础的抗震稳定性,并基于计算分析结果提出了相应的工程措施以确保厂房的安全运行。The powerhouse foundation of Longshou Ⅱ hydropower station in Heihe River has characteristics of active fault with large width of fracture zone and is in strong seismic region. According to the existing design specification, ANSYS is used to establish three-dimensional finite elements static and dynamic model of powerhouse foundation. Then the aseismic calculation results of powerhouse foundation are obtained under different conditions. At the same time, it demonstrates aseismic stability of the powerhouse foundation. Finally, the corresponding engineering measures are put forward to guarantee safety operation of powerhouse.
