摘要
This paper presents an experimental study of the factors influencing the volume of quicksand through underground boreholes for dewatering by exposing sand aquifers. The results show that the volume of quicksand increases with decreasing particle size of sand. For the same particle size of sand, the larger the diameter of the boreholes, the faster of speed of quicksand, and the volume of quicksand decreases linearly with time. While the diameter of the boreholes is smaller than 15 mm, the speed of quicksand is lower, and the curve of the volume of quicksand vs time is a parabola.
