Abstract: This paper is an application of laser holographic photoelasticity and quantitative analysis in the study of recent tectonic stress fields and seismicities in North china. Several points can be covered:1) In the area of North china the principal compressional stress trends ENE—NE;2) In this region right-lateral motion can be found on those faults trending ENE—NE and left-lateral one, on those trending EW and NE;3) Regions of stress concentration are Haicheng, Weifang, Linyi, Shijiazhuang, Yi-xian, Linfen, Huayin and Pingluo in North China.

摘要： 本文应用激光全息光弹、普通光弹实验方法和定量分析研究了华北地区现代构造应力场的分布特征与应力集中区的分布。1.华北地区主压应力轨迹线的方向是北东东向。2.华北地区北北东向和北东向断层是水平右旋运动的,近东西向和北西向断层是水平左旋运动的。3.华北地区应力集中区主要分布在海城、潍坊、临沂、石家庄、忻县、临汾、华阴、平罗等地。
