Problems solved by technology
[0003] At present, research on the mechanism of karst collapse at home and abroad is still in the qualitative or semi-quantitative evaluation stage. Quantitative calculations such as numerical simulation models are also researched under many assumptions, and there is generally a lack of high simulation degrees that can fully present the characteristics of field geological structures indoors. For the exploration of the mechanism of collapse, it is necessary to strictly adhere to the principle of controlling variables during the test, and conduct multiple sets of repeated tests under the test conditions of frequently changing single influencing factors. Once the current indoor model test platform is built, change the test Difficult conditions, long test period, and high cost, these factors more or less restrict the further development of physical model test research

The invention provides a simulation test system for the hydrodynamic induced collapse catastrophe evolution of a covered karst area. The simulation test system for the hydrodynamic induced collapse catastrophe evolution of a covered karst area comprises a main body test system, a water level and a rainfall control system and a monitoring and supervising system. A soil sample is filled with the main body test system to simulate the geologic structures of the unconfined aquifer and the confined aquifer; the water level and the rainfall control system simulate the water level change and the rainfall change through water supply, water level change and rainfall of a soil sample in a main body soil box and a soil sample in a karst funnel hollow box; and the monitoring and supervising system records the changes and the collapse catastrophe evolution process of the soil samples under different water levels and different rainfall conditions. The simulation test system for the hydrodynamic induced collapse catastrophe evolution of a covered karst area completely presents the field geological characteristics and the induced collapse influence factor loading effect of the covered karst area.
Description
technical field [0001] The invention relates to the field of geological disaster prevention and control, in particular to a hydrodynamic collapse catastrophe evolution simulation test device in a covered karst area. Background technique [0002] Karst collapse is one of the most common geological hazards in covered karst areas. Due to the remarkable characteristics of overburden karst collapse, such as suddenness, spatial concealment, diversity of influencing factors, and complexity of collapse mechanism, the research on the mechanism of karst collapse under complex environmental conditions has always been at the forefront of the field of earth science. [0003] At present, research on the mechanism of karst collapse at home and abroad is still in the qualitative or semi-quantitative evaluation stage. Quantitative calculations such as numerical simulation models are also researched under many assumptions, and there is generally a lack of high simulation degrees that can full...
