Title:
INDOOR TEST APPARATUS FOR MEASURING SEEPAGE EROSION CHARACTERISTICS OF MULTILAYER SOIL SAMPLES UNDER IN-SITU PRESSURE
Document Type and Number:
WIPO Patent Application WO/2020/228230
Kind Code:
A1
Abstract:
Disclosed is an indoor test apparatus for measuring seepage erosion characteristics of multilayer soil samples under in-situ pressure, comprising an experiment chamber body, a servo hydraulic loading system, a constant head water-pressure system, a vertical displacement sensor, a water flow sensor, a fine particle migration measurement system, and a computer integrated control system; the experiment chamber body is used for holding soil samples; the servo hydraulic loading system is used for providing the in-situ pressure of a normal load to simulate a soil sample; the fine particle migration measurement system is used for counting the mass of the fine particles washed out by the water flow in the soil sample under the effect of seepage; the computer integrated control system is used for controlling the operation of the experimental instrument and collecting, calculating, and storing the experimental parameters monitored by the sensors; the present apparatus can provide in-situ pressure and constant head seepage erosion conditions for multiple layers of soil samples indoors, and can also timely determine the change in the coefficient of permeability of the soil sample, the amount of settlement of the soil sample, and the amount of fine particles in each layer of the soil sample, and finally, analyze the seepage erosion characteristics of each layer of soil samples.
