Abstract

The invention provides a system and method for simulating evolution and disaster causing of deep toppling deformation. The system comprises a geotechnical centrifuge, a model box, a slope model, multiple differential displacement sensors and a high-speed camera; the geotechnical centrifuge is connected with the model box, the model box is used for providing placing space for the slope model, the slope model is placed in the model box, the differential displacement sensors are arranged on the slope model, and the high-speed camera is arranged on a hanging basket of the geotechnical centrifuge.The system and method for simulating the evolution and disaster causing of the deep toppling deformation have the advantages that a model having same characters with actual metamorphic rocks is constructed, the valley trenching action is simulated, the real natural environment is simulated by using a geotechnical centrifuge model, the evolution process of the deep toppling deformation is simulatedthrough centrifuge model tests of four stages, and finally, key factors and disaster-causing factors of the deep toppling deformation are obtained through simulation calculation according to collected data and pictures collected by the differential displacement sensors and the high-speed camera.

Description

technical field [0001] The invention relates to the field of geotechnical technology, in particular to a system and method for simulating the evolution of deep dumping deformation and disasters. Background technique [0002] Dumping deformation is the phenomenon that the layered anti-dip rock mass bends and breaks towards the free surface under the action of comprehensive forces such as gravity and in-situ stress. According to the mechanism and scale of occurrence, it can be divided into shallow dumping deformation and deep dumping deformation. Shallow dumping deformation generally occurs in reversed slopes composed of hard rock masses. The development time of this kind of deformation is short, and the rock layer will be broken when the bending deformation is small. [0003] Deep dumping deformation generally occurs in anti-dip slopes composed of flexible rock masses. This kind of deformation develops for a long time, and the rock layer will not break even if the bending de...
