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。
Aiming at the problems that the foundation of Huadian Longshe 2 hydropower station is active fault, the width of fault fracture zone is large and the strong earthquake zone is located, the three-dimensional finite element static dynamic model of plant foundation is constructed by ANSYS according to the requirements of current codes, The seismic calculation results of each working condition of the plant foundation are presented, the seismic stability of the plant foundation is demonstrated, and corresponding engineering measures are put forward based on the calculation and analysis results to ensure the safe operation of the plant.
