摘要
当堤基有深厚砂层时,堤防渗流稳定安全存在很大隐患。就此以罗溪中围天马河段堤防为例,利用曹洪教授编制的二维有限元剖面渗流分析程序对有覆盖层和无覆盖层的深厚砂层上的堤防渗流进行计算分析。然后针对不同情况采取不同的防渗措施,并通过程序计算分析采用防渗措施后堤防的渗流情况。
Significant risks exist in maintaining the embankment seepage safety when levee has deep sand.Taking Luoxi middle embankment of Tianma River for example,this article calculates the seepage and stability of embankment which has cover or no cover on the deep sand by applying Professor Cao Hong＇s two-dimensional finite seepage analysis program profiles.Then,seepage control measures are taken in various situations and the seepage control is analyzed through program calculation.
