| 摘 要： | 针对浅层不透水层下存在流动显著的地下水位路段,为降低地下水位修筑渗沟却无法布设出水口难题,提出了封闭式渗沟的新型地下排水构造型式,就封闭式渗沟的主要构造,施工要点做了简要介绍,重点阐述了封闭式渗沟的水力计算方法.通过算例验证了封闭式渗沟效果,表明封闭式渗沟是解决低洼平坦地带降低地下水的一种有效措施.

| Abstract: | The close underdrainage is introduced to solve the problem of setting underdrainage to lower the water table but difficult to set the outlet, where there is no natural water system but there is seepage under the upper terrain below the first shallow aquifer. The main structure, construction techniques, and particularly the calculating method about close underdrainage are presented in this paper. Validation with an example indi cates that the close underdrainage is an effective measure to solve the drainage problem in low lying flatness zones. |
