同马大堤堤基防渗方法研究

The study of seepage prevention methods of the Tongma main dike foundation

讨论了同马大堤堤身土质状况,对同马大堤堤基土层结构进行了分类,通过渗流计算提出了同马大堤典型断面堤基防渗处理措施。针对同马大堤堤基土层结构的特点,提出了堤基防渗处理的原则。堤防防渗方案的选择,必须顾及堤基土体的物理力学性质及堤基周围的人文及地理环境要素,同时应考虑到用于堤防防渗处理的经费,然后通过多种方案的比较,找出其中最为合理的堤防防渗处理措施。

Soil conditions of the dike body at Tongma main dike is discussed, and the structure of the soil layer of the dike foundation at Tongma main dike is classified. The measure to prevent seepage to the dike foundation of the typical segment at Tongma main dike is given by means of seepage calculation. Considering the characteristics of the structure of the soil layer at Tongma main dike, the principles to prevent seepage to the dike foundation at Tongma main dike are given. To choose methods to prevent seepage of the dike, the physical and mechanical property of soil of the dike foundation and cultural and geographical environment factors around the dike foundation must be considered, and the funds to prevent seepage to the dike must be considered, the appropriate measures to prevent seepage to the dike is decided by means of comparison of many methods.
