The invention belongs to the technical field of underground water monitoring and discloses an underground water on-line monitoring and early warning system and method for an expansible soil environment. The underground water on-line monitoring and early warning system for the expansible soil environment comprises a water level monitoring module, a soil displacement monitoring module, a central control module, an early warning module, a drainage module and an update display module. According to the underground water on-line monitoring and early warning method for the expansible soil environment, water level changes of expansible soil and a lower aquifer are measured through a water level sensor, meanwhile, a displacement sensor is arranged on the bottom interface of the expansible soil, soil displacement deformation is monitored, a threshold value alarm is set, and once the water level height reaches a critical value, or the displacement begins to change to a certain set critical value, an alarm is given, and a problem of water level rising is solved by automatically pumping underground water and draining water.
Description
technical field [0001] The invention belongs to the technical field of groundwater monitoring, and in particular relates to a groundwater online monitoring and early warning system and method for expansion and contraction soil environments. Background technique [0002] Expansion-contraction soil will expand and deform when it encounters water, which will affect the stability of engineering buildings. Especially in the distribution areas of expansive soils in major linear projects such as high-speed railways, expressways, and South-to-North Water Transfer Projects, the engineering stability of expansive soils seriously restricts the safe operation of the projects. Existing construction methods mostly carry out construction measures such as soil replacement or rapid closure from the surface to the depth range involved in foundation treatment to prevent expansion and contraction soil from being affected by precipitation, but in some areas, the aquifer at the bottom of expansio...
