Experimental equipment and method for simulating the evolutionary process of landslide-weir dam-dam failure flood disaster chain

摘要

[Summary] The present invention belongs to the technical field of rock soil construction and construction geology, and provides an experimental device and method for simulating an evolutionary process of a landslide-dam dam-dam failure flood disaster chain. The device includes a set of landslide power condition simulation system, a set of water power condition simulation system and a set of non-contact measurement system. The landslide power condition simulation system can simulate multiple types of landslide mass materials, landslide speed, landslide path width, length and tilt angle; the water power condition simulation system can simulate water flow rate, water flow velocity, river channel. It is possible to simulate multiple items of hydraulic conditions such as tilt angle and riverbed properties; the non-contact measurement system installed in the experimental equipment can be used for non-contact measurement from a single contact point measurement to the entire range. It can be realized and the measurement method is highly accurate and convenient. The present invention provides a reliable laboratory experimental simulation device and method for studying the flood disaster chain of landslide-dam failure-dam failure, which is simple in structure and convenient to use.
