某广场设计中存在无法满足抗浮要求及地基沉降过大等问题。在对多种抗浮方法进行比对的基础上,选择配重抗浮法进行抗浮处理,并采用SFIA方法进行了地基与基础协同作用计算分析,确定主楼采用CFG桩、裙房采用天然地基的合理设计方案。
There is a square design can not meet the anti-floating requirements and excessive settlement and other issues. Based on the comparison of various antifloat methods, the counterweight floatation method was selected for antifloating treatment. The SFIA method was used to calculate and analyze the synergistic effect between foundation and foundation. The CFG pile was used in the main building and the natural foundation Reasonable design.
