Abstract

The invention discloses a multi-factor coupling test system for researching an instability failure mechanism of a foundation pit and a side slope, and relates to the technical field of research test devices for the instability failure mechanism of foundation pit and side slope engineering. A transparent observation area is arranged on a side panel of a model test box, and a foundation pit or side slope model is arranged in the model test box; a vibration simulation system can apply vibration in the vertical direction and / or the horizontal direction to the model test box; a rainfall simulation system can simulate rainfall in the model test box; an underground water simulation system can inject confined water and / or diving water into the foundation pit or side slope model; a loading system can apply a load to the model slope crest; a temperature control system can control the temperature of the foundation pit or side slope model; and a test system can monitor and collect technical parameters in the soil body in the simulation test process. According to the invention, simulation test research on the deformation and failure process of the foundation pit or the side slope under the multi-factor coupling effect can be carried out, and a reliable basis is provided for stability evaluation and reinforcement treatment of the foundation pit or the side slope.

Description

technical field [0001] The invention relates to the technical field of a research test device for the instability and failure mechanism of foundation pit and slope engineering, in particular to a multi-factor coupling test system for studying the instability and failure mechanism of foundation pit and side slope. Background technique [0002] Groundwater seepage, rainfall and vibration loads are the main factors that induce instability and failure of foundation pits and slopes. The failure mechanism of foundation pit and slope under the combined action of multiple complex factors is particularly complex, and the current theory and technology are still difficult to analyze and calculate the multi-factor coupling problem well. Therefore, foundation pit and slope disaster accidents often occur under the combined action of complex factors. Although scholars at home and abroad have adopted various methods and done a lot of work on the instability of foundation pit and slope engi...
