摘　　要：近年的工程地震工作,如地震小区划、重大工程场地的危险性分析等,一般都要做设计谱标定。既反映局部场地条件,又反映地震环境的双参数标定设计谱的方法,已为工程界接受。作为该方法的应用,本文采用澜沧——耿马地震的强震资料,重新确定了设计反应谱的形状参数,给出了反映云南地区地震特性的设计谱,可供中、小型工业与民用建筑抗震设计时参考使用。Generally speaking, a calibration of design spectrum has to be done for all recent earthquake engineering work, such as the seismic micro-zoning, and risk analysis for major construction sites. The double-parameter calibrating method of seismic response spectrum, that reveals both site condition and seismic setting, has been accepted by enginearing circles, Being an application of the method, the strong motion data of Lancang-Gengma earthquake are used in this paper to determine the shape parameter of the spectrum. The design spectrum with its typical seismic characters in Yunnan Area has been presented, so as to provide references to the anti-seismic designs of intermediate and small sized industrial and civilian conshuctions.
