分层区块化吹填在超厚淤泥底质吹填区的应用

Application of stratified block fill in ultra-thick silt bottoming fill area

如果吹填物为砂质,而吹填区域为淤泥层,传统吹填施工很难解决吹填过程中吹填物对吹填区淤泥的破坏问题,会造成大量淤泥集中,给后续地基处理施工造成极大困难。如果吹填区域淤泥层过厚,而吹填施工速度过快,传统吹填施工还有可能造成吹填区失稳。结合巴拿马科隆集装箱港口(PCCP)工程,利用边坡稳定理论,探讨分层区块化吹填在超厚淤泥底质吹填区的应用,并提供一种区块化分层吹填的施工工艺,供相关工程参考。

If the dredger fill is sandy and the fill area is silt layer,it is difficult to solve the damage problem of silt caused by the dredger fill in the filling process by traditional blow-filling construction,which will cause a large amount of silt concentration therefore great difficulty in subsequent foundation treatment construction.If the silt layer in the fill area is too thick and the fill construction speed is too fast,the conventional fill construction may also cause the landfill to be unstable.Combined with the Panama Colon Container Port(PCCP)project,the slope stability theory is used to explore the application of stratified block filling in ultra-thick silt bottoming area.The construction process of a block layer fill is for reference of related projects.
