现场水下浇筑对淤泥固化效果的影响

Influence of underwater casting on mud solidification

根据现场固化淤泥的水下和陆上浇筑试验,分析比较了两种浇筑情况下固化淤泥的强度、变形以及填筑地基的承载力.试验结果表明,水下和陆上浇筑情况的固化淤泥填筑地基均能满足深圳盐田港集装箱堆场对地基承载力的要求,水下浇筑时只要控制好固化淤泥中的水不离析,反而能促进固化淤泥后期强度的增长.

Based on the in-situ tests of solidified mud casted under water and on land, the strength and deformation of the solidified mud and the bearing capacity of the casting foundation on two casting conditions are compared. Tests results show that the solidified mud casting foundation both under water and on land can meet the bearing capacity demands of the container yard of Yantian Harbor in Shenzhen city, and that underwater casting is favorable to the increase of the later bearing capacity of the foundation if the segregation between water and mud is controlled.
