Abstract

The invention relates to a device used for simulating a soil deformation process induced by stratum loss. With the device adopted, the problem that a soil body deformation process induced by stratum loss in a construction process cannot be simulated cannot be solved. The device comprises a test container, a long-strip-shaped building simulation object, a construction process simulation object anda soil body simulation object; the soil body simulation object and the test container jointly support the long-strip-shaped building simulation object; the construction process simulation object comprises a round hard tube; soil body simulation object leakage holes are formed in the side surface of the round hard tube; leakage hole switches can block the soil body simulation object leakage holes;the soil body simulation objects can only fall into the round hard tube from the soil body simulation object leakage holes in an open state; and the test container is provided with a light-transmitting wall. The use method of the device comprises a step of simulating a construction process: the leakage hole switches are opened at a construction propulsion speed, the soil body simulation object falls into the round hard tube through the soil body simulation object leakage holes in the open state. The soil body deformation process induced by stratum loss in the construction process can be observed through the light-transmitting wall, so that scientific research can be conveniently carried out.

Description

technical field [0001] The invention relates to the technical field of soil settlement measurement, in particular to a device and method for simulating the soil deformation process induced by formation loss. Background technique [0002] During the underground construction of tunnels, culverts, etc., stratum loss will occur, which may affect the soil structure above it, induce soil deformation, and endanger the structural safety of buildings in or above the soil. In practice, the impact of the construction process on the building structure in or above the soil should be considered before construction, so as to reduce the probability of accidents and the intensity of accidents as much as possible. Therefore, it is necessary to simulate the soil deformation process induced by stratum loss during the construction process to qualitatively understand the impact of stratum loss on the soil body or the building structure above it during the construction process, and to obtain test ...
