Thirdly, the thesis paid close attention to the isochrones of pore water pressure in the engineering cases of slope under the conditions different rates of change water level and raining by using numerical simulation on the basis of saturated-unsaturated theory. From the result, the change of groundwater and water level in front of slope is not synchronized .

结合工程实例，采用数值模拟，结合非稳定饱和-非饱和渗流理论，重点探讨坡前水位按不同速率变化及强降雨情况下，坡体内渗流场的时空分布特征，从计算结果得出，水位在上升或下降期，坡体内地下水位变化与坡前水位变化速率不同步，表明坡体内地下水位变化有明显的滞后特点。
