Title : Mechanical Analysis and Creep Deformation of Soft Rock Deformation Under High Ground Stress Conditions

Abstract :

Creep being a time-dependent deformation at elevated temperature and constant stress plays a crucial role in engineering and is now being employed for use in civil engineering projects. Its excellent properties in reducing stress concentrations and internal stresses will help reshape the future in terms of its influence in rock engineering. This paper gives an in-depth review on the mechanical analysis and creep deformation of soft rock deformation. Firstly, the composition and law of ground stress based on generalised Hoek-Brown criterion was reviewed. Then the mechanical analysis of excavation deformation of weak surrounding rock in terms of its basic characteristics and deformation mechanism. Finally, the creep of surrounding rock as well as the parameters of the Burgers creep model were discussed.
