Analysis of the expansion of cylindrical and spherical cavities in soil and rock provides a versatile and accurate geomechanics approach for study of important problems in geotechnical engineering. As the method getting more important, the analysis of non-circular shape cavity is becoming significance. The paper has investigated the cavity wall shape varying characteristic and elasto-plastic distribution of stress of elliptic shape cavity under internal uniform pressure during the expansion period through ABAQUS FEM numerical. It pointed that the elliptic cavity wall will tend to circle shape as the internal uniform pressure increasing. It also gain that the elasto-plastic distribution around the elliptic cavity is bigger than spherical cavity’s and smaller than spherical cavity’s when material and pressure are same . The stress characters and the cavity wall transfiguration result is useful for estimate non-circular shape cavity expansion.

Rock Rheology

As to the time effect of prestress in bolt in geotechnical engineering, the stress distribution in fully-grounded MFRP bolt and its trend influenced by rock rheology is obtained by FEM. The Burgers body which is able to model the primary and secondary creep regions of the rock mass is applied to analyze the time effect of prestress in MFRP bolt. The results show that rock rheology has a great effect on MFRP bolt stress.

Stress And Deformation

In this paper, the flexible modeling capabilities of ANSYS and the excellent nonlinear solving ability of ABAQUS were multiplied for simulating the deep 3D-excavation. The results illustrated that both advantages of two numerical analysis softwares were combined. The complex stresses and deformations of the deep 3D-excavation were exactly simulated. The approximate solutions show that this method could analyze the coupling effects between the soils and the walls of the 3D-excavation. It was a successful application of using advanced CAE technologies into geotechnical engineering.
