Abstract

The invention discloses a device for simulating the instability and damage of a collapsed rockfill body, which comprises a simulation box and a base. There are two arc-shaped slots on the inner peripheral wall of the bearing plate along the circumference of the bearing plate. The clamping block is slidably arranged in the arc-shaped slot. The upper end of the clamping block protrudes from the upper end surface of the arc-shaped slot. The sliding slot The two ends communicate with the lower ends of the two arc-shaped grooves respectively, and a ejector rod is provided on the output end of the upper cylinder, and the upper end of the ejector rod is hinged with an elastic metal strip, and a positioning groove is respectively opened in the middle of the two end faces of the vibrating cylinder , each positioning groove is provided with a driving cylinder, and a pin is connected to the output end of the driving cylinder. This program is used to simulate the stability of accumulations under different topographical conditions, record and analyze the corresponding experimental data, and then formulate corresponding measures to deal with accumulations under different topographical conditions to reduce losses caused by the collapse of accumulations .

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...
