Problems solved by technology

However, for soil-rock mixture slopes, when they experience long-term heavy rain, the seepage water pressure may be generated when the rainwater infiltrates into the soil, which will have a certain impact on the stability of the slope; on the other hand, considering the traffic load and earthquake load and other dynamic It is also necessary to study the dynamic properties of the soil-rock mixture

Abstract

The invention discloses a soil-rock mixture cyclic shear seepage test system characterized by comprising a horizontal loading system, a vertical loading system, shear boxes, a seepage water pressure loading system and a data acquisition and processing system; the horizontal loading system comprises a left horizontal loading system and a right horizontal loading system; the vertical loading system is arranged above an upper shear box and comprises a rolling shaft row, a force transmission plate, a vertical displacement sensor, a vertical load sensor and a vertical jack, and the shear box comprises a lower shear box and the upper shear box located above the lower shear box; the permeation water pressure loading system comprises a water pressure pump, a measuring cup, a water inlet pipeline and a water outlet pipeline; and the data acquisition and processing system comprises a data acquisition device and a data processing device. The invention further discloses a corresponding test method. Through the left horizontal loading system and the right horizontal loading system, cyclic loading of a soil-rock mixture can be achieved, various types of tests can be achieved, and guidance is provided for engineering practice.

Description

technical field [0001] The invention belongs to the technical fields of civil engineering, engineering geology, water conservancy and hydropower, transportation and other geotechnical engineering and disaster prevention and mitigation engineering, and specifically relates to a soil-rock mixture cyclic shear seepage test system and a test method thereof. Background technique [0002] my country is a country where geological disasters occur very frequently, especially in the southwest of my country, where there are a large number of loose deposits composed of landslide deposits, collapse deposits, residual deposits, ice collapse deposits, slope deposits, etc. These deposits mainly form In the Quaternary. The material composition of these deposits is composed of mixed media such as soil with gravel or block stones, and gravel or block stone with soil. Different from ordinary soil, it is a special geological body between soil and rock. Some scholars downplay its geological origi...
