摘要
在详细研究构造岩软弱夹层工程地质特性的基础上，对构造岩井壁的应力应变进行了细致分析。并根据岩石强度理论计算出井壁塑性变形区半径，可供建井部门在锚喷支护及设计注浆孔深时参考。
ased on intensive study of the engineering geological properties of tectonite weak seams, the stresses and strains of tectonite sidewalls are analysed and the radius of plastic deformation sone of the sidewall is calculated in accordance with the rock strength theory. The construction department can make reference to the results when designing the manner of anchor prop and depth of grouting hole.
