摘　　要：针对堤坝的非饱和稳定渗流问题,采用数值模拟方法,研究了在渗流作用下堤坝的浸润线变化情况,堤坝的非饱和区的负压变化规律等,为堤坝非饱和渗流在工程上的应用提供参考。There were unsaturated steady seepage phenomena in most levees. In this paper,the numerical simulation is employed to calculate the seepage through levees ,then the change of pore-water pressures and negative pressures in the unsaturated field of the levees are studied.The results could supply the application to the unsaturated steady seepage for reference.
