江西赣江丰城段防洪堤地质勘查与防渗措施

Geological survey and seepage control measures for flood dyke of Fengcheng section of Ganjiang River

防洪堤堤基工程地质情况与渗流模式对堤防除险加固与改建工程的质量具有重要影响。在江西赣江丰城段防洪堤除险加固与改建工程的前期设计工程中,对堤基的地质情况进行了实际勘查。根据地质勘查确定的各类土层分布情况及土体的物理力学性质,确定了堤基渗流的几种模式,并有针对性地拟定了堤基防渗处理方案,为该工程的建设打下了良好的基础。

The geological condition and seepage modes of flood dyke have a significant effect on the construction quality of dyke danger removal and reconstructing project.In the pre-stage design of flood dyke danger removal and reconstructing project of Fengcheng section of Ganjiang River in Jiangxi Province,the geological condition of dyke foundation was investigated.Based on the distribution condition of various soil layers and soil physical and mechanical features,the seepage modes of dyke foundation are determined and the seepage control schemes for the dyke foundation are proposed,which lays a foundation for the project construction.
