| 摘 要： | 杭州钱塘江南岸某大型内湖采用江底抽砂回填措施时,填入了大量江底淤泥,形成了深厚超软弱的填土地基,使后续的填土及建筑桩基工程施工无法进行。在多方案分析比较的基础上,通过现场试验,提出了分块、分级堆载固结的地基处理措施,并介绍了方案的实施要点。结合现场监测数据,分析了软基处理过程中地基沉降、孔隙水压力以及抗剪强度等的发展规律,结果表明排水系统的畅通与否直接关系到地基处理的效率,堆载在时间及空间上的合理安排是地基处理成败的关键,该项目的地基处理达到了预定的目标。

| Abstract: | A large lake located in Hangzhou is filled with marine got from the bottom of Qiantangjiang river.The deep soft clay make it difficult for the following backfill and foundation pile construction.A soft clay treatment method based on preloading drainage consolidation is proposed in this paper according to several foundation treatment schemes comparison and field test,and the key construction process is also introduced.Based on the field observation data,the deformation behavior,pore-pressure and shear streng... |
