绥中某电力设备站场区地震危险性分析

Seismic Risk Analysis of Some Electric Power Equipment Station in Suizhong

绥中某电力设备站是东北地区较重要的电力设施,场址位于长期隆起的绥中剥蚀丘陵上。通过现场实地勘察,获得区域、近区域地震活动、地质构造、地球物理场等资料,并对工程场址进行了地震危险性分析。按工程建筑物抗震设计规范要求,分别给出了50年63%、10%和2%超越概率水平的基岩峰值加速度及反应谱,计算出地震动参数,为该电力设备站建设提供了抗震设计依据。

Some electric power equipment station in Suizhong, as one of the significant electric power stations in Northeast of China, is located on Suizhong erosion hills of long-term bulge. Through in-situ prospecting, the data about the region and near region seismic activity, geological tectonics as well as the earth geophysical fields have been gained and, the seismic risk analysis of this site has been carried out. According to the need of design code for anti-seismic of engineering constructure, the bedrock peak acceleration rate and response spectrum of exceeding probability of 63%,10% and 2% are given respectively and seismic motion parameters are also calculated, which will provide the evidences for anti-seismic design of this electric power equipment station.
