Abstract
The invention discloses a heavy rainfall induced rock landslide field model testing device. The device comprises a rainfall system, a rain gauge, a flow controller, an artificially excavated crack, a simulation water line, a back edge crack water level, a clay compaction layer after artificial grooving, a natural soft interlayer, a stable bedrock layer, an upper rock mass, sensors, a drain pipe, an anti-slide pipe, a water pump, a water supply pipe, a control valve, a water meter, nozzles, three-way pipes, four-way pipes, two-way pipes, branch pipes and main pipes. The device eliminates errors caused by artificial production of slide zones and can simulate the effect degree of different rainfall degrees to landslides; the model has controllable structure size and has the characteristics of being high in flexibility, convenient to construct, short in period, capable of being reused and the like, and the cost is saved.
Description
technical field [0001] The invention belongs to the field model technical field of rock landslides, in particular to a field model test device for rock landslides induced by heavy rainfall. Background technique [0002] Landslide geological disasters have the characteristics of suddenness, variety, frequency and severity. Landslide disasters can account for 70% of all geological disasters every year, and rainfall is the main factor inducing landslides. In particular, rock landslides in eastern Sichuan are more sudden and have a high casualty rate, causing huge damage to people's lives and property. In recent years, many scholars have done a lot of research on the hazard mechanism, failure mode and treatment methods of rock landslides, and have achieved many results. Among them, first-hand data such as stress changes and deformation displacements inside the landslide mass are particularly important. If in-situ monitoring of stress, displacement, etc. is carried out on rock...
