Description

technical field [0001] The invention relates to a test device in the fields of geotechnical engineering test technology, environmental science and engineering, in particular to a submersible evaporation test device simulating the dynamic change of groundwater level. Background technique [0002] Submersible evaporation refers to the phenomenon that shallow groundwater is transported through the soil, transported to the surface and gasified and lost. Submersible evaporation is related to the retention, loss and salinization of soil water, which adversely affects the growth of vegetation and crops in the agricultural field. In the field of geotechnical engineering, submerged evaporation is the direct cause of many engineering problems, which is easy to cause problems such as subgrade churn and slope instability. Therefore, the study of phreatic evaporation is of great significance for soil salinization prevention and control, geotechnical engineering stability research, formu...
