Physical model test apparatus for confined groundwater in bedding bank slope

Abstract

The invention discloses a physical model test apparatus for confined groundwater in a bedding bank slope, which relates to the technical field of geotechnical engineering. The physical model test apparatus is helpful for analysis of influence of different external conditions on confined groundwater in the bedding bank slope and comprises a surface water infiltration simulation unit, a pervious bed test groove section, a reservoir water level fluctuation simulation unit and a measurement unit, wherein the pervious bed test groove section is obliquely arranged and filled with sandy soil, the surface water infiltration simulation unit has a water storage function and comprises a drain pipe which is inserted into sandy soil in the higher end of the pervious bed test groove section, the reservoir water level fluctuation simulation unit has a water storage function and comprises a seepage port which is connected with the lower end of the pervious bed test groove section, and the measurement unit is used for detecting the values of a confined water head in sandy soil. The physical model test apparatus provided by the invention can simulate generation and changing of confined groundwater phenomena, change laws of each influence factor and interaction between the structural characteristics of the bank slope and the environment.

Description

technical field [0001] The invention relates to a test device that considers the influence of geological structure conditions (dip angle of permeable layer, permeability) and bank slope environmental conditions (reservoir storage and discharge rate, water level, bank slope groundwater recharge conditions) on the confined water of bedding landslides. It is used to carry out simulation experiments of confined water changes under different permeability, different slope angles, different water level rise and fall speeds, and different recharge conditions, and at the same time study the mechanism of confined water on bedding bank slopes, which belongs to the technical field of geotechnical engineering. Background technique [0002] Reservoir landslides have always been highly valued by the government, engineering circles, and academic circles. my country has made great progress in landslide disaster management, landslide mechanism research, and landslide control in reservoir areas...

Problems solved by technology

[0002] Reservoir landslides have always been highly valued by the government, engineering circles, and academic circles. my country has made great progress in landslide disaster management, landslide mechanism research, and landslide control in reservoir areas. However, bank instability incidents still occur from time to time. serious personal and property damage

However, the model has poor applicability in structurally strong bank slopes, and cannot explain the phenomenon that most landslides or bank deformations occur during the impoundment period of the reservoir
