Device and method for simulating influences of drying and watering cycle action generated by water level variation of fluctuating belt of reservoir on reservoir bank slope rock masses

Abstract

The invention discloses a device and a method for simulating influences of drying and watering cycle action generated by water level variation of a fluctuating belt of a reservoir on reservoir bank slope rock masses. The device comprises a test chamber and a sample bracket arranged in the test chamber; one end of a screw rod is mechanically connected with a motor outside the test chamber, and the other end of the screw rod extends into the test chamber; the screw rod is provided with impellers; the upper end of the test chamber is provided with an admission pipe, an air release valve and a rock adding hole; the rock adding hole is provided with a top cover; a water outlet is formed in the lower end of the test chamber; a flow heater is arranged in the test chamber; a ventilation hole is formed in the side face of the test chamber; the ventilation hole is communicated with an air blower. The method comprises the step of repeatedly conducting a rock sample wet environment test and a rock sample dry environment test so as to simulate a test environment in the test chamber more truly. The device and the method disclosed by the invention that more accurate tests are realized by simulating different flow rates, water pressure states and different periods of drying and watering cycle, so that the controllability of test variables is higher, and follow-up related test study can be conveniently performed.

Description

Technical field [0001] The invention involves a device and method that affects the impact of the dry wet circulation effect caused by the lift of the water level of the water level of the decoration of the reservoir. technical background [0002] The stability problem of a large number of shore slope needs to be understood by the library bank to disappear water-rock-rock action mechanism. The existing experimental equipment simulation conditions are not real, the test data deviations are large, which is not conducive to follow-up research.The impact of the test device pays more attention to qualitative analysis and research, and the quantitative research on continuous changes in the surface of the rock is quite weak. Invention content [0003] The purpose of the present invention is to provide an experimental device and method that simulates the mechanism of water-rock-rock-to-rock-shore, and achieves more accurate experiments by simulating the speed, water pressure state, and d...

Problems solved by technology

[0002]The stability of a large number of bank slopes needs to understand the mechanism of water-rock interaction in the drawdown zone of the bank. The simulation conditions of the existing experimental equipment are not true, and the test data deviates It is not conducive to follow-up research. The existing research methods are affected by the test equipment, and more emphasis is placed on qualitative analysis and research. The quantitative research on the continuous change of the rock surface is quite weak.
