Triaxial or polyaxial strength of rocks is required while analysing many civil and mining
engineering structures in rocks. Mohr–Coulomb criterion is the most widely used strength …

Rocks encountered in foundations of heavy structures are invariably intersected by
discontinuities (joints). In the past, several studies have been performed by researchers to …

This paper aims to assess the lateral limit load (H) of a pile embedded in cross-anisotropic
clay deposits by a three-dimensional (3D) finite-element lower bound theorem in association …

The parameter mi is an important rock property parameter required for use of the Hoek–
Brown failure criterion. The conventional method for determining mi is to fit a series of triaxial …

Recent research has paid little attention to the shear damage of discontinuities with different
joint wall material (DDJM). In this paper, we present an investigation on the evolution of the …

Since rocks are aggregates of mineral particles, the effect of mineral microstructure on
macroscopic mechanical behaviors of rocks is inneglectable. Rock samples of four different …

Under the triaxial compressive state, the compressive strain is supposed to happen in the
direction of the maximum principal stress, but tensile strain happens in the direction of the …

Hoek-Brown 准则作为应用最广的岩石强度准则之一, 其主要有2 个方面的局限性: 1)
在常规三轴高围压条件下, 根据Hoek-Brown 准则预测的强度与试验实测的强度数据偏差较大; …

It is well recognised that the strength of rock masses depends upon the strain history, extent
of discontinuities, orientation of plane of weakness, condition of joints, fill material in closely …

The recommended bearing capacity of medium weathering mudstone foundation is less
than the capacity of the rock structure to withstand loads in Southwest China. A …
