Abstract

The invention discloses a device for simulating a slope with a seepage-freezing-thawing coupling action and a using method thereof, and is mainly used for simulating the stability of the slope with the seepage-freeze-thawing coupling action. A seepage effect mainly comprises a rainfall system and a groundwater system, the rainfall system is mainly used for simulating the stability of the slope under different rainfall intensity and time conditions; the groundwater system is mainly used for simulating the stability condition of the slope under the conditions of different groundwater heights, and in the device, the stability of the slope under a confined water condition and the stability of the slope under a diving condition can be simulated. A freezing-thawing system mainly consists of a freezing device, a rainfall water source and a groundwater source, and is used for simulating the stability of the slope under the freezing condition and the spring thawing condition of a slope body inwinter. A seepage working device and a freezing-thawing working device in the system not only can work independently, but also can work cooperatively and jointly, so that the slope stability monitoring is completed jointly, and reliable experimental data and technical support are provided for engineering design.

Description

technical field

[0001] The invention belongs to the field of geotechnical engineering, and in particular relates to a slope device and a use method for simulating seepage-freeze-thaw coupling action. Background technique

[0002] The stability of slopes under seepage-freeze-thaw coupling conditions has always attracted the attention of many experts and scholars. The static and dynamic effects and physical and chemical softening effects of water on the slope seriously affect the stability of the slope, especially for rock and soil slopes under freeze-thaw and precipitation conditions. According to statistics, most landslide accidents occur in the rainy season and spring melt period, and the factors that induce landslides are related to the effects of precipitation and spring melt. Seepage of groundwater, rainfall and vernal infiltration will cause changes in pore water pressure in the slope body, and at the same time, physical and chemical softening of water will also lead t...
