【摘要】 本文通过对发生在云南省的澜沧—耿马等几次地震记录的分析，提出了适合云南实际的地震动反应谱特性Ｖｍａｘ／ａｍａｘ值的ｗｅｉｂｕｌ模型，并求出了平均值和标准差，对于样本不足的给出了ｍ，η的置信区间，可为我国、特别是云南省的工程建设提供基础依据。更多还原

【Abstract】 By analyzing the records from the Lancang-Gengma earthquakes in Yunnan Province, Weibull model which is suitable to practical earthquake ground motion response spectra V max /a max is presented and the mean values and standard deviations are obtained. The confidence interval of m, η is offered for small space size. This model will provide a basis for engineering construction in China, especially in Yunnan Province.更多还原
