| 摘 要： | 运用FLAC软件对杭州开发区某办公楼复合地基沉降进行数值模拟,结合工程实际对FLAC模拟结果进行了位移矢量和沉降分析,并将数值模拟结果和实测沉降值进行对比. 在对数值模拟结果和实测数据进行深入分析的基础上,总结出影响CFG桩复合地基沉降的主要因素. 分析发现桩土相互作用、桩的设置、载荷时间关系和土层应力分布对复合地基沉降影响显著.

| Abstract: | Composite foundation settlement of an office building in Chinese Hangzhou development region was numerically simulated with FLAC software.According to engineering practice,displacement vector and settlement analyses on the simulated results were carried out,and the calculated settlements were compared with the measured ones.On the basis of the research on the numerical simulation results and measured settlement data,main factors influencing CFG pile composite foundation settlement were summarized.It is found that composite foundation settlement was obviously affected by pile-soil interaction,pile setting,load-to-time relation and soil stress distribution. |
