为了防止渗流水经过强透水基础渗漏,采用了截水墙等专门的防渗设施,其与坝体连接大多是通过沿坝趾铺筑的横向不透水板,可保证坝体必要的防渗强度。进行有截水墙的土坝设计时,重要的是能够准确计算截水墙在大坝基础中最合理的位置及其参数。 In order to prevent percolation water leakage through the strong pervious foundation, the use of a special seepage control devices such as cut off walls, the connection with the dam body is mostly horizontal impermeable plate paved along the dam toe to ensure the necessary dam seepage strength. When designing embankments with cutoff walls, it is important to be able to accurately calculate the most appropriate location and parameters of cutoff walls in the dam foundation.
