Description
Technical Field
The invention relates to the technical field of geotechnical engineering, in particular to a transparent soil model test device and a test method for simulating the influence of an underground retaining wall structure on groundwater seepage.
Background
The significant difference along the river slope is that the presence of river (reservoir) water alters the hydrodynamic conditions of the near-river side slope. The water lifting of the river (warehouse) breaks the original stress and seepage state of the landslide in the aspect of mechanical balance. When the water level of the river (the reservoir) suddenly drops, the response hysteresis of the groundwater is obvious, so that the overall form of the groundwater level line becomes steep, a water head difference is formed, and the dynamic water pressure effect is generated on the landslide body. Leading to frequent occurrence of dynamic deformation and destabilization damage along the river slope.
The retaining wall is arranged on the water facing side of the side slope, and the rock-soil body behind the wall is closed. The energy exchange is continuously carried out between the seepage field and the stress field of the rock-soil body. Groundwater seepage can not only change the water pressure in the rock and soil body, but also influence the distribution of soil pressure, thereby influencing the stability of the side slope. The underground retaining wall structure has a large influence on groundwater seepage, however, the conventional experimental method cannot directly observe the change of the seepage field in the soil body.
Therefore, developing a transparent soil model test device for researching the influence of the underground retaining wall structure on groundwater seepage, visualizing the change of the groundwater seepage field, and has great significance for exploring a scientific method for preventing slope disasters.
