Vacuum tube dewatering method and light well point method have been widely used in engineering dewatering and foundation treatment.
However, there is little research on the calculation method of unsaturated seepage under the effect of vacuum pressure which is generated by the vacuum well.
In view of this, the one-dimensional (1D) steady seepage law of unsaturated soil in vacuum field has been analyzed based on Darcy’s law, basic equations, and finite difference method.
First, the gravity drainage ability is analyzed.
The analysis presents that much unsaturated water can not be drained off only by gravity effect because of surface tension.
Second, the unsaturated vacuum seepage equations are built up in conditions of flux boundary and waterhead boundary.
Finally, two examples are analyzed based on the relationship of matric suction and permeability coefficient after boundary conditions are determined.
The results show that vacuum pressure will significantly enhance the drainage ability of unsaturated water by improving the hydraulic gradient of unsaturated water.
