Patent number: 11982649Abstract: A shear testing system and method of thermo-seepage-mechanical field and engineering disturbance coupling under deep and complex condition are provided. The shear testing system can be used in conjunction with an axial pressure application device to simplify the structure, save costs, and facilitate a triaxial confining pressure—temperature—axial pressure—torsional shear coupled test on a rock specimen. The shear testing system can achieve the following three purposes. First, the shear testing system can convert an axial pressure into a torsional shear force through a transmission mechanism of a power conversion assembly. Second, the shear testing system can apply an axial pressure to the rock specimen fixed between two specimen fixing heads, through a pressure shaft of an axial pressure mechanism. Third, the shear testing system can apply a triaxial confining pressure and a temperature field to the rock specimen.Type: GrantFiled: January 16, 2024Date of Patent: May 14, 2024Assignee: SICHUAN UNIVERSITYInventors: Jianfeng Liu, Heping Xie, Chao Ma, Fujun Xue, Jingjing Dai, Jianxiong Yang, Lu Wang, Zhijun Wu, Xiangchao Shi, Houquan Zhang, Yinghui Ma, Tao Meng, Defu Zhu, Shaoqi Kong
