地壳变形与地应力变化关系的研究

地震地质研究表明，地壳变形与地应力变化直接相关，它们之间存在着比较复杂的关系。本文在分析甘肃东南部地区地应力及地壳变形观测资料的基础上，结合其它前兆物理现象的对比，用数值模拟方法，研究了地应力变化与地壳形变、地震活动性以及区域构造活动之间的关系。其方法和结果拓宽了不同观测资料横向综合分析的路子，使其在地壳动力学、地震地质研究和地震预报中得到更广泛、更进一步的应用。

STUDY ON THE RELATIONSHIP BETWEEN CRUSTAL DEFORMATION AND VARIATION OF GROUND STRESS

Studies of seismogeology show thst the crustal deformation directly relates to the variation of ground stress, but the relationship between them is relatively complicated. In this paper,on the basis of analyzing the ground stress and crushal deformation obervations in southeast Gansu and comparimg them with other precursory physical phenomena, the relations of ground stress chsnges to crustal deformation, seismicity and regional tectonic activity are studied by using the method of numerical simulation. The method and the results further developed the way by which different observations are comprehensively analyZed eras wise,and might make the microinformations be widely applied to the studies of crust dynamics and seismogeology, as well as earthquake prediction.
