摘要
岩体初始地应力场是地震预测和岩体工程设计的重要依据之一,根据实测地应力资料,采取一定的数值分析方法,反演出整个计算区的初始地应力场。本文综述了国内外地应力场的研究现状,介绍并分类归纳了几种典型的地应力场研究方法,并对每个方法的适用范围进行了评价,对以后地应力研究的发展方向提出了建议。
Initial geostress field is one of the most important factors in earthquake prediction and geotechnical designs. According to the initial geostress measurement results, with the numerical analysis method used, the initial geostress field of the calculation area can be obtained. Some typical analytical methods of initial geostress are classed and concluded in this discourse. The disquisitive actuality in the world are introduced. The applying bound and the opinion of each method are given and the analytical direction of initial stress is suggested in this paper.
