Abstract
Provided is a clamp of elastic box of stiff true-triaxial testing system and a displacement monitoring method for cuboid specimens. The clamp includes six pressing plates and eight plate springs, which form an elastic pressure box. One surface of the elastic pressure box can be disassembled, which simplifies the steps of rock sample mounting, and saving the mounting time. The springs connected with the pressing plates ensures the stability of the clamp but cannot affect the stress state of other surfaces of the rock sample during the test of the rock sample, thereby ensuring test accuracy. The invention further provides a displacement monitoring method for the rock sample by using the elastic box clamp. Six displacement sensors are mounted on the elastic box clamp, and the displacement of the rock sample can be monitored in real time.
