摘要
文章通过规则齿形结构面在不同法向应力下的剪切试验,对其力学特性进行了基础性研究,阐述了规则齿形结构面在剪切条件下力学特性的主要特征及其力学特性的主要规律。通过对试验数据的分析,对结构面在剪切力作用下的强度特性以及结构面在剪切条件下的粗糙度特性进行了研究,在此基础上提出了结构面剪切刚度计算模型以及结构面爬坡角与粗糙度系数之间的经验关系,同时对结构面的剪切位移曲线特征进行了描述,并对现象做出了解释。
In this paper, a series of shear tests under different normal stresses were carried out on regular dentate rock mass discontinuities. The paper discusses the mechanical properties and main law of regular dentate rock mass discontinuity under shearing. Through the analysis of test data, it carries on further investigation on strength properties and roughness characteristics of discontinuities. On this basis, the shear stiffness model and the empirical relationship between climbing angle and roughness coefficient are proposed. Meanwhile, it carries on research to the shear curves of the discontinuities under the shear condition.
