摘要
本文通过对福建省惠安县前林东埭海堤进行水力坡降计算,对后排型防渗以及中间截渗型防渗方案比较后采用压渗盖重法进行渗流控制设计,有效地消除了堤后管涌险情,取得了良好的效果.
Qianlin-Dongdai sea dike was built in the 1990s. It is the masonry structure and is constructed by the local villagers. The construction is non-standard by the restricted economy and technology. Meanwhile, the sea dike operated for many years which is aging and need repairs. The risk such as piping and seepage appeared already. Through the calculation of the hydraulic grade and the comparison of the cover weight anti-seepage plan behind dike and the dike foundation vertical anti-seepage plan, the seepage control design was done by the cover weight method. The piping risk is eliminated and the effect is good.
