Abstract

The invention provides a multi-field coupled loess-mudstone landslide disaster simulation test device and method. The upper part of a test box is provided with a rainfall device and a temperature control device; a mudstone occurrence controller is arranged at the bottom of the test box, a mudstone simulation layer is arranged above the mudstone occurrence controller, and the mudstone occurrence controller is composed of a thin plate, a steering plate arranged below the thin plate, a hinged support, a telescopic rod and a hydraulic jack; the direction of the thin plate in the space is freely and flexibly adjusted through the steering plate and the hinged support to simulate the occurrence of different mudstones in the loess-mudstone slope, the height of the thin plate is adjusted in cooperation with the telescopic rod and the hydraulic jack, and the requirement for the position of the mudstones in the loess-mudstone slope is met. The formation and development rules of cracks in the loess slope are known, the inducing reason and the damage mode of the loess-mudstone landslide are explored, and the loess-mudstone landslide disaster is quantitatively evaluated.

Description

technical field [0001] The invention belongs to the technical field of geological disaster model tests, in particular to a multi-field coupled loess-mudstone landslide disaster simulation test device. Background technique [0002] Loess is widely distributed in my country, and loess-mudstone landslides, as one of the most important geological disasters in Northwest China, occur frequently, spread widely, and have strong disaster-causing ability. With the increase of extreme weather, loess-mudstone disasters appear Out of the prone and frequent situation. Facing such a severe situation, the related research work on loess-mudstone landslide disasters is imminent, which is of great significance to protect people's lives and property safety, so as to better serve the needs of disaster prevention and mitigation. [0003] Due to the strong water sensitivity of loess, that is, the water content in loess has an important influence on the mechanical properties of loess, and the loose...
