摘要
采用桩筏基础分析方法,针对六边形平面形状和非均匀布桩的桩筏基础工程实例进行非线性分析,得到了基础沉降、桩轴力、摩阻力和筏与桩的荷载分担比随施工进度的变化规律,在一定程度上揭示了桩与土的共同作用机理.同时,将沉降计算结果与现场观测数据进行比较,显示了较好的一致性,表明该计算结果是合理可靠的.
The analysis method for piled raft foundations is applied to the computation of the engineering example with nonuniform layout of piles and hexagon raft. The average settlement, differential settlement, axial force of pile, friction of pile, percentage of load taken by raft and their changing rules as construction rate of progress are gained. These results reveal interaction mechanism of piles and soil to a certain extent. The comparison of the settlement results with the field observations shows a preferable identity and suggests that the results are reasonable and reliable.
