Ground fracture site hazard simulation device and method considering underground water

Abstract

The invention provides a ground fracture field hazard simulation device and method considering underground water. The device comprises a test box which comprises a box body, and the box body employs arectangular box body structure with an upper opening; a ground fracture interface filling body is obliquely arranged in the box body and divides the box body into an upper panel area and a lower panel area, and simulated soil layers are arranged in the upper panel area and the lower panel area; a first water supply pipe is arranged at the bottom of the upper panel area; a second water supply pipeis arranged at the bottom of the lower panel area; water inlet systems are respectively arranged at two ends of the box body and are respectively communicated with the first water supply pipe and thesecond water supply pipe; drain pipes are uniformly arranged at the bottom around the box body. Simulated soil layers are filled on two sides of the ground fracture interface filling body, and the simulated soil layers and the ground fracture interface filling body are combined to form a simulated ground fracture site; by arranging the water inlet systems and the water supply and drainage pipes,the water level in the simulated ground fracture site is adjusted, and ground fracture site harm caused by groundwater changes is effectively simulated.

Description

technical field [0001] The invention belongs to the technical field of geological disaster analysis, in particular to a ground fissure site hazard simulation device and simulation method considering groundwater. Background technique [0002] The ground fissure is a kind of discontinuity or discontinuity phenomenon of the rock-soil medium developed on the surface of the earth's crust, which is caused by factors such as internal and external forces and human activities; The related geological disasters caused by the rupture of near-surface soil layer have caused direct or indirect losses of billions of dollars. [0003] So far, many scholars at home and abroad have carried out a lot of research on the mechanism of ground fissures, activity characteristics, types of disasters, and control measures, and have achieved rich results; using indoor experiments to simulate ground fissures, the results can be Higher reliability and diversified monitoring items can better reveal the co...
