Abstract

The invention discloses a collapse rockfill instability failure simulation device, which comprises a simulation box and a base. The lower surface of a bottom plate is provided with two hanging boards.Each hanging board is provided with an upper positioning hole, a horizontal hole and a lower positioning hole. The inner circumferential wall of a bearing plate is provided with two arc grooves in the circumferential direction. A clamp block is slidably arranged in each arc groove. The upper end of each clamp block protrudes out of the upper end surface of the arc groove. The two ends of a sliding groove are communicated with the lower ends of the two arc grooves respectively. The output end of an upper ejector cylinder is provided with an ejector rod. An elastic metal strip is hinged on theupper end of the ejector rod. The two end surfaces of an oscillation tube are respectively provided with a positioning groove in the middle. Each positioning groove is internally provided with a driving cylinder. The output end of the driving cylinder is connected with a pin column. The device is used for simulating stability of accumulation bodies under different geographic and geomorphic conditions and recording and analyzing corresponding experimental data, so that corresponding measures corresponding to the accumulation bodies under different geographic and geomorphic conditions are made to reduce loss due to collapse of the accumulation bodies.

Description

technical field [0001] The invention relates to a rockfill body slide simulation experiment, in particular to an indoor experimental device for simulating a secondary geological disaster source after an earthquake—the instability and destruction of a collapsed rockfill body. Effective implementation of rock mass instability protection measures. Background technique [0002] There is a common type of secondary geological disaster source in the southwestern region of my country where earthquakes occur frequently---collapsed rock-fill bodies, which are usually precipitous rock groups in mountainous areas that are triggered by strong earthquakes to collapse and slide, and large-scale rockfalls accumulate on the slope corners of the mountain made. Collapsed rockfills have the characteristics of significant material structure differentiation, random accumulation shape, loose accumulation metastable, sudden collapse and collapse, etc., which often bring great safety hazards to adja...
