摘　　要：介绍采用计算机程序“利用断层面上擦痕的观察、测量计算主应力轴状态”来求得区域构造古应力场状态,进行动力学分析的有关注意问题;野外如何进行数据的采集和室内如何分析、计算每个点的局部应力场状态。介绍如何从局部分析区域应力场特征及区域应力场演化与构造变形、构造演化的关系及意义。This paper points out notable problems concerning the use of the program Computation of Principal Stress Axes by Observing and Measuring Striations on Fault Planes to evaluate the paleo stress field state of regional strucutre and make dynamics analysis,then discusses approaches to collecting data in the field,making indoor analysis and computing local stress field state of each point,and finally introduces the way of locally analyzing regional stress field characteristics,the relation of its evolution with structural deformation and evolution,and the implications.
