The selection way for the mechanical parameters of a jointed rock masses is given in combination with the Hoek-Brown strength criterion. Then, a numerical calculation model is constructed by utilizing 3DEC numerical simulation software to discuss the stability of the adjoining rock under the condition...

However, the conventional method involving the determination of disturbance coefficient (D) cannot reflect the anisotropic characteristics of strength of jointed rock mass when considering mining damage. A numerical analysis method is proposed to determine the value of D using jointed rock damage tensor ...
Strength of a model of jointed rock In an attempt to extend the presently limited state of knowledge of the strength of jointed rock masses, triaxial compression tests were carried out on ide... ET Brown,DH Trollope 被引量: 101发表: 1970年 Shear Strength of Rock, Rock Joints and Rock Mas...
Determination of the strength of jointed rock masses is an important and challenging task in rock mechanics and rock engineering. In this article, the exis
The strength of jointed rock mass is strongly controlled by the degree of interlock between its constituent rock blocks. The degree of interlock constrains... N Bahrani,PK Kaiser - 《岩石力学与岩土工程学报(英文版)》 被引量: 0发表: 2020年 Strength of massive to moderately jointed hard rock ma...
A simple empirical failure criterion is presented and its application in engineering design is illustrated by means of a number of practical examples. (Author/TRRL)doi:10.1680/geot.1983.33.3.187HoekE.GeotechniqueHoek, E. , Strength of jointed rock , Geotechnique , 33 , 187 – 223 , 1983 ....
1) strength of jointed rocks 节理岩体强度 1. Based on an improvingstrength of jointed rocksand presenting the mean-square shear stress, a yield criterion is derived. 在一个改进的节理岩体强度和提出均方剪应力基础上,导出一个屈服准则,结合断裂力学理 论,推导出一新的微裂纹区域,最后与Mises屈服准则的推...
Construction of dams, tunnels and slopes in jointed, water-bearing rock causes complex interactions between joint deformation and effective stress. Joint deformation can take the form of normal closure, opening, shear and dilation. The resulting changes of aperture can cause as much as three orders...
