Calculation Model of Multi-Well Siphoning and Its Feasibility Analysis of Discharging the Groundwater in Soft Soil

The use of a siphon is drainage method that does not require the external power, and siphons are used extensively in practice. application treatment soft soils has become popular approach recent years. Analyzing change water level multi-well siphoning basis siphons. calculation model established through equivalent transformation. A finite difference to solve model, accuracy verified by comparing results with test field tests. Using numerical feasibility soil demonstrated from two aspects, i.e., well spacing permeability coefficient. show both “minimum drop increase” “average increase”, as decreases or increases When coefficient 1 × 10−8 m/s 2 m, decrease approximately 9.72 m after 100 days drainage. It feasible apply technology discharge groundwater soil.
