真空联合堆载预压法处理吹填淤泥地基的设计与施工

Design and Construction of Hydraulic Mud Fill Foundation Treated by Vacuum Prepressing Method Combining with Dumping

珠海电厂厂区原海域部分须进行填海造陆 ,设计利用港池疏浚淤泥作为填海造陆土料 ,并采用真空联合堆载预压法对吹填淤泥地基与原基土进行加固处理 ,介绍真空联合堆载预压法加固吹填淤泥地基的设计和计算方法 ,以及施工过程。工程加固结果显示该方法技术先进 ,加固效果可靠 ,且使工期缩短 ,造价降低 ,取得了显著的经济效益。

Part of sea area should be filled to build the Zhuhai Power Plant.In the design the mud dredged from the basin was used as filling material and the hydraulic mud fill foundation and original underlying soil were reinforced by vacuum prepressing method combining with dumping.This paper presents the design,calculation method and construction course of hydraulic mud fill foundation treated by vacuum prepressing method combining with dumping.Results of reinforcement show the method is technically advanced with reliable effects,shortening construction period and lowering costs,thus achieving significant economic benefits.
