Experimental study of land reclamation by dredged spoil from Xiamen Harbour;

Developing such equipment has the significance to speed up the land reclamation for Tianjin Port.

Through analyzing the requirement of sea reclamation project,this paper expatiates about the application of vacuum preloading drainage consolidation method in large-scale sea reclamation project.

The geologic structure, stratum, geomorphy and the features of geologic settlement of quaternary period in Macao District were briefly introduced in the paper and the significance of studying and analyzsing the geological condition of coastal engineering for sea reclamation were pointed out in it.

In the formation of sea reclamation region,backfill only experienced short time with most filling material of excavated-stone,so the loose structure,large interstice,smooth connectivity of underground water & sea water and strong scouring by tidal action existed,which brought difficulties in borehole completion and slurry solidification for water-proof curtain construction.

Based on the analysis on construction methods for large-scale sea reclamation project in Beibu gulf and classification of mechanism of different rock and soil combinative characteristics;and according to the foundation treatment and construction experience of different projects in this area,the optimized methods of construction and treatment for different ground and foundation were summed up.

The general engineering situation,engineering condition,engineering design and construction,and engineering characteristics of retaining dike reclamation project of Jiangsu Datang Lusi Power Plant are presented.
