中国黄土山城“依山造居”的几个灾害问题讨论──黄土层地震反应分析

A Discussion on a Few Hazards in Construction Along Loess Mountain in China──Analysis of Loess Seismic Response

以兰州市皋兰山为例对黄土层地震反应作一研究，利用二维有限元分析法，求出黄土山不同部位在未来５０年１０％超越概率的地震危险水平下的建筑场地地震反应谱及场地自振周期。这些参数可作为各种建筑物和构筑物的抗震设计参数．

Taking Gaolan Mt.,Lanzhou,as an example,loess seismic responses are analyzed and theseismic response spectrum and other relatcd seismic parameters of the construction sites in differentplaces of 0.1 surpassing probability in 50 years obtained,providing the construction design with nec-essary anti-seilsmic parameters。
