摘要
通过对宝鸡和兰州地震小区划中所获得黄土震陷数据的统计,对黄土震陷的影响因素如含水量、孔隙比、干密度、初始弹性模量进行了分析,得出了对震陷初判更实用、更为具体的多项指标标准,并对弹性模量应用于黄土震陷的判断进行了探讨。
Based on the statistic data of loess seismic subsidence from the seismic micro-zoning works in Lanzhou and Baoji, many influence factors on the subsidence such as water content, void ratio, dry density and initial elastic modulus are analysed, and some more available, more concrete initial judging criterions for the loess seismic subsidence are obtained. Meanwhile the application of initial elastic modulus to the judging work is discussed.
