Macro-meso failure mechanism and strength criterion of frozen weakly cemented sandstone under triaxial unloading

Qing‐Hai Deng, Hao Fu, Junchao Wang, Xiaobiao An et autres

Introduction In the excavation engineering of tunnels and mines in the western cold region, the unloading failure zone is mainly caused by stress release. This study aimed to investigate the deformation and failure mechanism of frozen weakly cemented sandstone (FWCS) when the …

Mechanical behaviour and macro-micro failure mechanisms of frozen weakly cemented sandstone under different stress paths

Xiaobiao An, Xianzhou Lyu, Sun Jiecheng, Zhukai Liu et autres

Significant unloading failure zones in artificial freezing shaft sinking projects in western China are primarily caused by stress release. To investigate the deformation and failure mechanisms of frozen weakly cemented sandstone (FWCS), three groups of triaxial unloading tests were conducted under different …

Experimental Study on the Damage and Deterioration Behaviour of Deep Soft Rock under Water-Rock Interaction

Zenghui Zhao, Hao Liu, Xianzhou Lyu, Lei Wang et autres

The ageing disintegration, the damage, and failure mechanism of water-saturated soft rock are of significance to hazard prevention for deep mining. In this paper, indoor experiments, including disintegration behaviour tests in water, uniaxial compression failure tests of rock samples with different water …
