疏浚泥固化处理进行填海工程的现场试验研究

疏浚泥固化处理后用作填方用土是疏浚泥处理的有效方法，但在我国还没有在实际工程中应用过。结合我国实际条件，在现场进行了疏浚泥固化处理的施工、浇筑，并对填筑地基进行了取样强度试验和原位静力触探试验研究。结果表明固化土的强度随水泥掺加量的增加呈线性增长，浇筑地基取样的强度比室内制样强度降低10％～50%，填筑地基的承载力可以满足填海工程地基设计的要求，疏浚泥固化处理土可以用作填海工程的材料。

Field Experiment of Dredged Spoil Solidified with Cement for Marine Reclamation Works

Dredged spoils being treated by solidification method provides an effectual way to convert dredged spoils into useful filling materials. The method has not been used in practical projects in China. The authors carried out an in-situ experiment of dredged spoils stabilized by cement at Yantian Port, Shenzhen, China. The unconfined compression tests and in-situ Static Cone Penetration tests were conducted on the foundation pits filled with stabilized dredged spoils. The unconfined compression strength has a linear relationship with the cement content, the strength of samples taken from the foundation decreased 10%-50% to that of samples made in the laboratory. The bearing capacity of the spoil-filled foundation can meet the demand of port engineering, and dredged spoil solidified with cement may be used as fill material for marine reclamation works.
