【摘要】 为研究抗震缝两侧不同基础形式地基沉降的变化规律,以北京某多层建筑为例,利用FLAC软件对抗震缝两侧采用不同基础形式后的地基沉降进行了数值模拟,结果表明,基础形式的改变对地基沉降有很大影响,并探讨了造成沉降分布规律不同的原因,指出采用条形基础时,应通过沉降分析确定基础的合理宽度．更多还原

【Abstract】 In order to study the rule of the settlement of ground after seam of seismic two sides,which use the different foundation forms,taking some multilayer construction in Beijing as an example,numerical simuta- tion has been conducted by using of FLAC.The results show that the distribution of settlement are quite dif- ferent when strip and raft foundations are used respectively and the reasons caused these differences have also been analyzed.It pointed out that when using the strip the foundation reasonable width of it should be gained through the settlement of ground analysis.更多还原
