摘要
土堤在沿江地区防洪体系中应用广泛,在内河和外江水位差作用下,土堤内部产生渗流,易引起土堤的变形、滑坡、渗流和渗透破坏。在东江流域范围内,堤防内部在汛期和枯水期分别产生非稳定渗流和稳定渗流,极易影响堤防安全。文章以电排站所处堤防为例,利用Autobank软件,选取最不利工况,对堤防现状渗流稳定进行计算。
Earth dike is widely used in flood control system along the river,under the action of water level difference between inner and outer rivers,seepage occurs in the internal soil dike,which is easy to cause deformation,landslide,percolation and seepage failure of the earth dike.In the range of Dongjiang River basin,unsteady seepage and steady seepage occur in the levee during flood season and dry season respectively,which can easily affect the safety of the levee.In this paper,taking the levee where the power discharge station is located as an example,Autobank software is used to select the most unfavorable conditions and calculate the current seepage stability of the levee.
