High-position dangerous rock mass protection structure impact response multi-dimensional large-scale simulation test equipment

Abstract

The invention discloses high-position dangerous rock mass protection structure impact response multi-dimensional large-scale simulation test equipment which comprises an artificial slope surface, hoisting equipment, a multi-angle slope surface vibration response device arranged on the artificial slope surface and a multi-direction impact response device arranged on the bottom plane of the artificial slope surface. A cantilever of the hoisting equipment is located above the response device, an impact mass block is hung on a walking lifting hook on the cantilever, and a wireless intelligent inclinometer is arranged on the impact mass block; a high-speed camera and a flash velocimeter are arranged on the artificial slope surface; and a high-speed camera is arranged on the periphery of the multi-direction impact response device. The equipment has the functions of adjusting test parameters in real time along with changes of uncertain environments, slope angles, different structural surfaces and earth surface conditions, analyzing dynamic impact characteristics of collapse rockfall of high-position dangerous rock mass, and depicting the whole process of starting, transporting and impacting the collapse rockfall; and the research on the coupling effect of the block-slope-engineering structure system in each process of the collapse rockfall movement is realized.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a multi-dimensional large-scale simulation test equipment for the impact response of a high-risk rock mass protection structure. Background technique [0002] In a complex geological environment, high-risk rock mass diseases have the characteristics of large number, large scale, complex types, high frequency of occurrence, and high degree of harm. building. For example: the Sichuan-Tibet Railway is the railway with the highest altitude, the most complex geology, and the most difficult engineering in the world planned and built along the Himalayan orogenic belt in the southeast of the Qinghai-Tibet Plateau. This area is the area with the strongest neotectonic movement in mainland my country. They are mainly distributed along the Yarlung Zangbo River along the Milin-Lang County, Two Bridges and One Cave-Lhasa section, and most of them are collapsed (dan...
