Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] The purpose of the present invention is to provide a kind of simulated landslide dam formation and dam failure experimental device and experimental method, to solve the problems in the prior art, so that the whole process of the landslide body discharging and blocking the river can be truly simulated, so that the experimental results are more accurate. Authenticity and less error.

[0028] In order to make the above objects, features and advantages of t...

Abstract

The invention discloses an experimental device and experimental method for simulating landslide barrier dam formation and dam break. The experimental device comprises a soil material sliding module, a water flow supply module, a water tank module and a tailing collection module; the water flow supply module is communicated with the tailing collection module through a water tank of the water tank module; the water flow supply module is higher than the tailing collection module; the water tank module is arranged on one side of the water tank; the soil sliding module is arranged on one side of the water tank and can push soil into the water tank; the water flow supply module can provide stable water flow; the tailing collection module can collect soil particles and water after an experiment; and the water tank module and the tailing collection module are each provided with a high-definition camera. The inclination angles of a landslide groove and an experiment water tank can be adjusted, and the outburst of a dam body under various experiment conditions can be simulated; the tailing collection device can screen discharged soil according to different particle sizes, so that grain gradation analysis of dam-breaking soil is facilitated, data support is provided for research on dam-breaking problems of the dam body, indoor simulation experiments can be conveniently carried out, and disassembly and assembly are convenient.

Description

technical field [0001] The invention relates to the technical field of landslide river blocking dam experiments, in particular to an experimental device and method for simulating the formation and failure of landslide dams. Background technique [0002] Dams generally include artificial dams and natural dams. Landslide blocking river dams are natural dams, which refer to the occurrence of landslides along the river or on both sides of the river under certain geological activities and extreme weather. The high-speed landslide debris continuously slides into the river, gradually Accumulated, and finally formed landslide blocking river dam. There are generally three types of river blockage by debris bodies: slide-in type, climbing type, and turn-back type. According to the debris type of the dam, the dam body can be divided into rock landslide body dam, soil landslide body dam, and collapse landslide body dam. Compared with artificial dams, landslide dams often have the char...
