Problems solved by technology
[0004] (1) Most of the landslide simulation experimental devices use a fixed slope angle, which is not flexible, and the representativeness of the obtained data is limited, which cannot well meet the purpose and requirements of the experiment
[0005] (2) Landslides can be divided into rock landslides and soil landslides according to the type of medium. Most of the experimental devices are single and cannot have both the functions of testing soil landslides and rock landslides. However, the experimental devices that can be used for rock landslides do not consider the impact of rainfall on landslides. landslide impact
[0006] (3) Most of the conventional measurement devices use sensors. Because the size of the sensor is relatively large compared with the model test box, in order to reduce the influence of the movement of the sensor on the soil disturbance around the sensor, it is necessary to increase the size of the test box, which makes the volume of the test device bigger

The invention belongs to a geological disaster model testing system, and in particular relates to an experimental system for simulating raining-caused landslide. The system comprises a test box, a landslide testing device arranged in the test box, a rainwater simulating device arranged on the test box, and a water collecting device arranged below the test box. According to the system, a spray head switch is adjusted to simulate the rainfall, so that the landslide parameters under different raining conditions can be tested; the system is compact in structure, convenient to use, dismount and mount, firm, durable, vivid in simulation environment, and relatively high in reliability of the obtained experimental data.
Description
technical field [0001] The invention belongs to a geological disaster model test system, in particular to a rainfall-induced landslide simulation test system. Background technique [0002] my country is a country with frequent occurrence of geological disasters. There are many types of disasters, wide distribution and serious disasters. The annual loss caused by geological disasters is nearly 10 billion yuan, of which landslide disasters account for 70%. Especially the landslide damage caused by rainfall is particularly serious, which affects people's lives. Huge damage was done to property and national economic construction. Over the years, a lot of research has been done on the disaster-causing mechanism, causative mechanism, forecasting and prevention and treatment of landslide disasters at home and abroad, and fruitful results have been obtained. When the landslide enters into rapid sliding, it is difficult to observe the deformation and damage inside the slide body, and...
