The testing device is simple in structure and convenient to use, and a reliable indoor test simulation device and a reliable indoor test simulation method are provided for research of a landslide-barrier dam-dam break flood disaster chain.

Description

technical field [0001] The present invention belongs to the technical field of geotechnical engineering and engineering geology, and in particular relates to the field of physical experiment simulation research of the whole process of landslide blocking river evolution. Aiming at the current lack of simultaneous simulation of landslide dynamic conditions and hydrodynamic conditions, as well as difficulties in collecting experimental data, a proposal is made. A test device and method for simulating the evolution process of a landslide-dam-break flood disaster chain. Background technique [0002] Large-scale slopes or high slopes along both sides of the river in mountainous areas are prone to damage and instability under disaster loads such as earthquakes and heavy rains. It keeps decreasing, and finally terminates at a certain position in the river bed or reaches the opposite bank and is broken and disintegrated by the collision of mountains, causing landslides to block the r...
