圈围工程软弱地基沉降监测分析

摘要

With the steady increase of the land usage ,exploiting usable land becomes a crucial factor affecting the development of the urban area of Shanghai.Land reclamation can be an effective alternative to solve the land shortage.In recent years,the land reclamation has received extensive attention and rapid development;however,such reclamation has become more and more challenging since the geotechnical and geological situa-tions have become more and more complicated.Based on a real project ,this paper presents how to utilize field monitoring data to control embankment construction rate and determine.This paper can be an important refer-ence for the practice of similar structures.%随着上海城区用地量的不断增加，土地资源成了影响上海发展的重要因素，围海造地成为政府和开发单位缓解土地紧张的一个必要手段，近年来，圈围造地的速度日益加快，而圈围工程的难度也不断增加。本文通过工程实例，介绍圈围工程中沉降观测成果在控制施工期加载速率及确定堤顶预留超高所起到的作用，为类似工程提供参考。
