两条断层相交或相距较近,由于构造应力的迭加,在交会处或两侧锐角部位,形成比原两条断层范围更宽、构造岩更为破碎的破碎带,即称为断层交会破碎带。这是一种常见的地质现象,不少工程在坝基、边坡、地下洞室等主要建筑物部位出现,成为影响建筑物基础稳定 Due to the superposition of tectonic stress, the two faults are intersected or located close to each other. At the intersections or sharp corners on both sides, the fault zone is formed wider than the original two faults and the tectonic rocks are more broken, which is called fault intersection crushing band. This is a common geological phenomena, many projects appear in the main building parts such as dam foundation, slope, underground caverns, etc., which will affect the stability of building foundation
