围海造陆工程中分层吹填工艺的研究

Technology of layered back filling in coast reclamation project

对分层吹填法进行总体介绍。通过具体工程实例,在固结时间、沉降量以及抗剪强度等方面对分层吹填法以及传统的直接吹填法进行深入比较。结果表明:采用分层吹填法的地基土体固结时间远低于采用直接吹填法,其地基沉降情况及抗剪强度也优于直接吹填法。

This paper gives a general introduction of layered back filling method. According to a specific project, this paper also makes in-depth compares between the layered back filling method and the traditional direct back filling method in the consolidation time, the sedimentation volume and the shearing strength. The result reveals that the consolidation time of the foundation with the layered back filling method is much less than that with the direct back filling method, and the sedimentation volume and shearing strength with the layered back filling method are also better than those with the direct back filling method.
