Abstract

The invention discloses an analysis testing device for simulating influences of rainfall and moisture content on side slope stability. The analysis testing device is composed of a side slope rainfall simulating system, a side slope testing platform system and a data acquisition analysis system, wherein in the side slope rainfall simulating system, a loop is composed of a water tank and a water pipe; the water pipe is provided with a water pump, a valve, a flow meter and shower nozzles; the shower nozzles are uniformly distributed at the top of the side slope testing platform system; in the side slope testing platform system, an inclined platform is located on a bottom plate; a thread rod and a rotary wheel connected with the thread rod are arranged under the bottom plate; a photographing wall is parallel to the rotary direction of the inclined platform; in the data acquisition analysis system, sensors are uniformly arranged on the bottom plate; a camera is located on the photographing wall and a sensor data collection device is arranged at one side of the bottom plate; and the sensor data collection device and the flow meter are connected with a computer by data transmission lines respectively. The analysis testing device has the advantages of high precision, simplicity and convenience for operation, and strong repeatability.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering tests, in particular to an analysis test device for simulating the influence of rainfall and water content on slope stability. Background technique [0002] Slope instability has brought great threats and losses to the safety of human life and property, and is a serious and adverse geological disaster. According to research reports, rainfall is one of the main causes of slopes, and the study on the deformation, disintegration and failure mechanism and stability of rock-soil slopes under the action of rainfall has very important theoretical significance and practical engineering value. The prevention and treatment of slopes in rainy areas has important guiding significance. At present, theoretical analysis and numerical simulation methods are mainly used to study the mechanism and process of rainfall-induced slope, mainly to study the relationship between rainfall, rainfall in...
