Problems solved by technology

Existing research methods and devices cannot obtain the parameters needed to study landslides induced by confined water layers. At the same time, the current research on slope timing prediction mostly focuses on the mathematical processing of slope time-displacement curves. In short-term forecasting or Slip prediction is reasonable, but this kind of curve is not monotonous and smooth, and is often an irregular broken line, which makes it difficult to judge the slip state of the slope intuitively and easily, and brings certain difficulties to disaster prevention and mitigation.

Embodiment Construction

[0020] Such as figure 2 , image 3 As shown, the upper surface of the test bed 8 and the horizontal plane are the required landslide inclination angle for the test, which is set as α here, and the cuboid test box 7 is arranged on the test bed 8, and the test box 7 is 1.35m long, 1.1m wide, and 5cm thick. It is evenly divided into 9 independent compartments along the length direction, and the compartments are respectively marked as No. 1-9 from the bottom right to the top left. Each compartment has its own water inlet device and pressure measuring tube 17, which is installed on the The middle of the side of the small compartment, so that the pressure in the tank is measured by measuring the height of the water column in the tube 17, which is considered to be the average pressure in the small compartment, which is also the pore water at the bottom of the bedrock above which the chamber corresponds average pressure, the upper surface of the test box 7 is provided with uniform p...

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 ...
