Abstract

The invention discloses a geological disaster chain simulation test device and method. The geological disaster chain simulation test device comprises a model box, a water injection box, a pipeline, a lifting device, a rainfall simulation device and a water level changing device. The model box is a cuboid of a frame structure, the side face of the model box is a breast board, the bottom face of the model box is a bottom plate, one side of the bottom plate is hinged to the side face of the model box, the bottom plate can overturn around a hinged hinge shaft, and the lifting device is connected below the bottom plate and located on the ground. The rainfall simulation device is located at the top of the model box and comprises a plurality of nozzles facing the interior of the model box; the water level changing device comprises a plurality of water injection pipes, a plurality of through holes are formed in the soil baffle and / or the bottom plate, and the water injection pipes are slidably connected into the through holes; the water injection pump is arranged in the water injection tank and is connected with the spray head and the water injection pipe through pipelines. By means of the device and method, special complex geological structures induced by simulating loess plateau disaster chains and multi-type disaster chain simulation tests can be met.

Description

technical field

[0001] The invention belongs to the field of geological disaster chain research and relates to a geological disaster chain simulation test device and method. Background technique

[0002] The terrain of the Loess Plateau in my country is vertical and horizontal, the loess structure is loose and porous, and the heavy rainfall causes frequent geological disasters such as landslides, collapses, mudslides, land subsidence and subsidence, and ground fissures, and the disasters are often chained. The suddenness is strong and the scope of influence wide and dangerous. In recent years, major construction projects on the Loess Plateau, such as creating cities by leveling mountains, improving ditches, and consolidating ditches to protect plateaus, have strongly transformed geomorphic units, forming a large number of excavated and filled slopes and large-scale landfills. Special excavation-fill and landfill interfaces, deep fill bodies, and rising groundwater levels all...
