Experimental study on unloading induced shear performances of 3D saw-tooth rock fractures

Qian Yin, Xinxin Nie, Jiangyu Wu, Qi Wang et al. • International Journal of Mining Science and Technology (2023)

A fractal model governing saw-tooth fractures was first introduced to replicate sandstone samples containing an inclined 3D penetrating rough fracture surface with various joint roughness coefficients (JRC). In conventional triaxial compres...

Stress-dilatancy properties for fiber-reinforced sand

KONG Yu-xia , SHENG Fei-fan , WANG Hui-juan • Yantu gongcheng xuebao (2018)

It is observed that randomly distributed polypropylene fibers act to interlock particles and thus improve the mechanical behavior of the reinforced soils. The polypropylene fiber inclusion clearly increases the shear strength of soils, and ...

Physical model test study on shear strength characteristics of slope sliding surface in Nanfen open-pit mine

Zhigang Tao, Yu Shu, Xiaojie Yang, Yanyan Peng et al. • International Journal of Mining Science and Technology (2020)

A physical model for the footwall slope of Nanfen open-pit mine, China was established using a self-developed deep geological engineering disaster model test system. A thermosensitive similar material, paraffin, was selected to simulate a w...
