Abstract

A test device consists of test box, water supply system and landshide body set on the test box. It is featured as presenting test table top surface to level as required dip angle, separating box inner cavity into several independent chambers connected to several independent water supply, setting water outlet hole on box top surface; forming landslide body from bottom to top with clay layer, water insolating layet and sliding layet. A method for detecting surface flow displacement is also disclosed by the present invention.

Description

technical field

[0001] The invention relates to a water-induced landslide simulation test device and a slope displacement monitoring method. Background technique

[0002] Under natural conditions, there are many reasons for landslides, and the interaction of various factors eventually leads to disasters, among which landslides caused by impermeable layers are the most common. Generally speaking, the impermeable layer is a clay layer, which is also a soft interlayer in the landslide. This interlayer can easily form a sliding surface under the action of gravity and groundwater. , the surface of the landslide is a few meters to more than 10 meters thick and is densely structured and extremely poorly permeable silty clay, and between it and the sliding surface is broken rock mass with good water permeability, and the slide bed is mudstone with poor water permeability. Broken rock masses are exposed at the trailing edge and there are creeping and pulling cracks distributed. The ...
