摘 要：
根据汉江城固段堤防工程土料室内试验资料与河堤、堤基土料分布,运用渗流理论和有限元法,通过多方案计算分析,研究了该段粉沙土河堤发生渗透破坏的机理,分析了1998年"8·20"洪水造成河堤背水坡脚和附近农田内发生渗透破坏的主要原因,提出了防治渗透破坏的工程措施。

摘 要：
According to the laboratory test data of soil and soil distribution in the body and foundation of the dike of Chenggu Section of Hanjiang river,by means of permeability theory and the FEM,the mechanism of the osmotic failure of the dike by the silt soil has been studied via several schemes.The main reason of the osmotic failure in the nearby farm and the slope bottom of the back slope of the dike in the "8·20" flood in 1998 was analyzed,a recommended preventive engineering measure is put forward.
