抛石促淤堤上筑堤基础处理方案选择

Scheme Selection of Foundation Treatment on the Sea Embankment Based on the Dam of Dumped Rock and Siltation Acceleration

20世纪七八十年代,为促进滩涂发展,浙江省不少滩涂未经基础处理而进行简单的抛石促淤。现在,滩涂适合围垦的条件已成熟,但筑堤的难度却因未进行基础处理的抛石促淤堤而增加。以西沙门围垦工程海堤为例,分析了利用抛石促淤坝(未经地基处理)建设海堤时,基础处理方案的比选与确定。

During the development process in the 1970s and 1980s,a large amount of beach was treated without foundation construction in Zhejiang Province.Now it is the proper time for beach reclamation,but the difficulty of dam was increased by the dam of dumped rock and siltation acceleration without foundation treatment.This paper took the sea embankment of Xishamen reclamation engineering for example,analyzed the problems of sea embankment engineering based on the dam of dumped rock and siltation acceleration(without foundation treatment),selected and determined the scheme of foundation treatment.
