本文主要探讨了设计堤与土坝时如何考虑渗流影响的问题。文中在谈到堤或土坝的一般稳定条件后,接着论及了各种情况下(长期壅水、短期壅水、坝在透水地基与不透水地基上等)透过坝体与坝基渗流的近似计算方法与渗流对土坝稳定的影响,同时区分了连续地下水流与单一水流通道的地下水运动。此外还讨论了设计土坝的诸原则与计算方法;在计算方面主要考虑了坝坡一般稳定性与局部稳定性的计算,以及带有滤层排水设备的规格。全文内容分四章:1.土坝稳定的条件;2.透过堤坝的渗流计算;3.渗流对土坝稳定的影响;4.土坝的设计。
This paper mainly discusses how to consider the influence of seepage when designing dike and earth dam. After discussing the general stability conditions of embankments or earth dams, the paper then discusses the seepage through the dam body and the dam foundation under various conditions (long-term sluice, short-term sluice, dam on pervious foundation and impervious foundation, etc.) Approximate calculation method and seepage flow on the stability of earth dam, at the same time distinguish between continuous groundwater flow and single water flow channel groundwater movement. In addition, the principles and calculation methods of designing earth dam are also discussed. The calculation of the general stability and local stability of dam slope and the specifications of drainage equipment with filter layer are mainly considered in the calculation. The full text is divided into four chapters: 1. Condition of earth dam stability; 2. Seepage through dykes; 3. Effect of seepage on earth dam stability; 4. Earth dam design.
