一、引言共轭破裂构造由相互交叉的两组断裂组成,在地壳岩石中十分常见。李四光称其为“棋盘格式构造”;张文佑称其为“X”型构造系,并做出共轭破裂构造形成的实验;丁国瑜认为,我国广大区域普遍存在现今正在活动的北东和北西方向共轭的地壳破裂网络图像:张四昌对我国11次强震共轭破裂构造特征进行了总结,认为主震前后出现与主 I. INTRODUCTION Conjugate fractured structures consist of two groups of faults intersecting each other and are very common in crustal rocks. Li Siguang called it a “chessboard format”; Zhang Wanyou called it the “X” tectonic system and made an experiment on the formation of a conjugate rupture structure; Ding believes that there are ubiquitous North-East and North-West activities currently underway in many areas of our country Yoke crust rupture Network image: Zhang Sichang summarized the structural characteristics of the 11th strong earthquake conjugate rupture in our country,
