长江重要堤防防渗与垂直防渗墙技术

Technolgy of the Vertical cutoff wall and waterproof managment in dyke building along Yangtze River

历来长江中下游堤防洪水险情不断 ,堤基渗漏、堤身隐患、河岩崩塌是三大主要险情 ,而堤基渗漏尤其突出。本文阐述了堤基渗漏的地下渗流场 ,依渗流规律制定渗流控制措施 。

The dangerous situation of flood is continuous all the time for the levee in the middle and lower reaches of Yangtze Rever.The three main dangers are bank infiltration,latant resk of levee body and bank slough.Under seepage field of bank infiltration,the important one,is discussed.Acoording to the seepang rule,the processing methods are draw up.Many vertical cutoff wall technologies,main measure of vertical in permeation,are describled in detail and the examples are given in the paper.
