Description
Technical field
The utility model belongs to slope stability testing field, more particularly to a kind of Reservoir Water Level slope stability experiment
Device.
Background technology
In hydraulic engineering, during sudden lower in water level, the phenomenon of slope instability easily occurs for the side slope on storehouse bank both sides.
In sudden lower in water level, now the volume of soil skeleton and effective stress all there is one from initial state to new state transition
Process, and the infiltration coefficient very little of cohesive soil, water is extruded, and the skeleton of soil is transitioned into new void ratio, can not be in a short time
Realize.In this way it is possible to an additional pore water pressure field to be dissipated with the time occur, pore water pressure is by acting on soil
Caused by total stress on body unit changes.This pore water pressure, just it is the immediate cause for causing many engineering accidents.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of Reservoir Water Level slope stability experimental rig, can
In the case of simulating sudden lower in water level, the interstitial hydraulic pressure value changes situation of side slope different parts, so as to Reservoir Water Level side
Slope stability is predicted.
In order to solve the above technical problems, technical scheme is used by the utility model:A kind of Reservoir Water Level side slope is steady
Qualitative test device, including testing stand, chamber and side slope analogue body, side slope analogue body are placed in chamber, and chamber is put
In on testing stand, chamber connects the first water pump by water pipe, and multiple space hydraulic gages, the space are set in side slope analogue body
Hydraulic gage is connected by data wire with data handling system.
In preferable scheme, including storage tank, the second water pump is connected by water pipe between storage tank and chamber.
In preferable scheme, first pump outlet sets funnel.
In further scheme, water tank with strainer is set, the upper end of water tank with strainer sets filter below the funnel.
In further scheme, the filter includes screen pack and activated carbon, and the activated carbon is arranged on two layers
The centre of screen pack.
In further scheme, the 3rd water pump is connected by water pipe between the water tank with strainer and storage tank.
A kind of Reservoir Water Level slope stability experimental rig provided by the utility model, by adjusting taking out for the first water pump
Water speed, the different rapid drawdown speed of reservoir level can be simulated, realized to different rapid drawdown speed side slope interstitial hydraulic pressure value changes
The measurement of situation.In preferable scheme, the storage tank of setting and the second water pump, it is not necessary to artificially carry out water filling, and pass through tune
The speed of drawing water of the second water pump is saved, can be with the rate of climb of Control experiment case water level, so as to simulate the process of reservoir level rising
In.The water tank with strainer of setting, the water discharged in chamber can be filtered, so as to realize experiment water circulation use.
