软弱结构面一般指在上下盘坚硬岩层间充填有一定厚度的软弱岩层或破碎物质的结构面。这种结构面的规模比较大,延展性好,破碎带宽度大,是构成岩体块体滑动与控制岩体稳定的重要因素。对于它的力学特性,近几年来我们做了一些研究,本文仅是一个简单总结。一、软弱结构面的形态特征软弱结构面的形态,大体可分为四种:1.平直的;2.起伏的;3.台阶状的;4.囊状的。 The weak structural plane generally refers to the structural plane of a layer of weak rock or broken material that is filled with a certain thickness between hard rocks in the upper and lower plates. This type of structural plane has a large scale, good ductility, and a large width of the fracture zone, and it is an important factor that constitutes the sliding of the rock mass and controls the stability of the rock mass. For its mechanical properties, we have done some research in recent years. This article is only a brief summary. First, the morphological characteristics of the weak structural surface The structure of the weak structural plane, can be roughly divided into four types: 1. Straight; 2. Ups and downs; 3. Step-like; 4. Capsule-like.
