数值计算验算了降雨的方式，斜坡地层的形状以及坡度的变化对地下水位进展和衰退过程的影响。
In numerical calculations, the effects of rainfall pattern, shape of slope layer and changing slope to the development and decline of subsurface flow were examined.
为掌握滨海地带无压含水层中的海水楔因地下水位升降及抽水引起的移动规律，采用室内实验的方法，考察了海水楔在不同的水面坡度和抽水位置下的移动特性。
This paper takes as its target at exploring the regularities of the seawater wedge encroachment and attacking influence on the coastal line groundwater level change through laboratory experiments.
抽汲地下水降低了地下水位，使上覆土层浮托力减小，水力坡度和流速增大，潜蚀作用加强。
Due to groundwater pumping the water level is lowered, the buoyancy in covering soil is decreased, the hydraulic gradient and flow velocity are increased, and the corrosion is enhanced.
