Landslide physical model test equipment under dry and wet circulation effect

Abstract

The invention discloses landslide physical model test equipment under dry and wet circulation effect. The equipment comprises a box body, a reservoir water simulation system is set at one side of thebox body; an underground water level adjustor is set at the opposite side of the reservoir water simulation system; a drying system is set on the top of the box body; an artificial rainfall system isset below the drying system; the artificial rainfall system is connected with a water supply system; the drying system comprises a group of heating light bulbs and blowing equipment; the artificial rainfall system comprises a group of water supply pipes; and spray nozzles are connected with the water supply pipes. According to the equipment, a landslide test under a wet and dry alternation condition can be simulated, the test is relatively practical, and accuracy of the test is improved. According to the equipment, different targeted test schemes also can be designed, and the landslide tests under different influence factors can be simulated.

Description

technical field [0001] The invention belongs to the field of geological disaster model tests, in particular to physical model test equipment for landslides under the action of dry-wet cycles. Background technique [0002] The geological disaster model test can directly observe and record the deformation and failure process of the disaster body; at the same time, the changes of various parameters inside the model can be obtained through monitoring sensors, so as to analyze the stress distribution and changes in each stage of the disaster body catastrophe process. Thanks to its own advantages, the geological hazard model test has developed rapidly. In recent years, great progress has been made in model materials and testing technology, which makes quantitative analysis possible in geological disaster model tests. [0003] In recent years, Hu Xiuwen, Tang Huiming, etc. (2005) conducted physical simulation experiments on the stability of Zhaoshuling landslide, determined the re...

Problems solved by technology

Droughts occur from time to time, and the rainfall is mostly concentrated in June-August. The study of geological disasters from a single influencing factor is not in line with the actual situation. The previous physical simulation experiments of landslide hazards were mostly studied from the aspects of rainfall or reservoir water, while drought conditions However, it is often overlooked that there is a lack of a disaster simulation device that can consider the conditions of alternating dry and wet conditions as a whole, which leads to the lack of accuracy of the test.
