| 摘 要： | 桩筏基础产生差异沉降的原因是基础底部的支承刚度分布不均匀,可以通过改变部分桩长来调整基础刚度分布的方法来解决。工程实测值和数值模拟分析表明,中间采用长桩,边角采用短桩可以减小差异沉降,在计算中需要引入地基土非线性特性。

| Abstract: | The cause of differential settlement of piled raft foundation is that the supporting stiffness below the foundation is nonuniform.Adopting different lengths of piles to adjust the basement stiffness can solve this problem.The test and numerical simulation results show that using long piles in the middle and short piles at sides can decrease the differential settlement,and the nonlinear characteristic of soil should be taken into account in calculation. |
