摘　　要：以江西某堤防工程为例,针对该堤防所存在的设计标准较低、堤身质量不高、渗漏及管涌严重等病害实际,通过方案比选推荐使用垂直铺塑防渗技术;并对该技术下所使用的造槽机械、塑膜材料、垂直铺塑施工过程等展开分析。防渗加固效果表明,垂直铺塑截渗技术能有效增大堤防结构渗径,消除剩余水头,降低外溢点水力坡降,避免行洪过程中堤防发生渗透破坏,取得较为理想的防渗加固效果。Taking a dike project in Jiangxi province as an example,in view of the problems of low design standard,low quality of the dike,serious leakage and piping,through the scheme comparison,the anti-seepage technology of vertical plastic spreading is recommended,and the technology used under the groove-making machinery,plastic film material,and vertical paving plastic construction process are analyzed.The effect of anti-seepage reinforcement shows that the technique of vertical plastic spreading can effectively increase the seepage diameter of levee structure,eliminate the remaining water head,reduce the hydraulic gradient of overflow point,and avoid the seepage damage of levee in the course of flood discharge,and obtain a relatively ideal effect of seepage prevention and reinforcement.
