| 摘 要： | 桩基础设计时如何考虑桩间土的承载能力，目前还是一个难题，通过对南京大学MBA大楼疏桩筏板基础的原位测试，得到了高层建筑疏桩筏板基础的沉降特性、桩顶压力分布、桩间土压力分布、筏板内钢筋轴力的分布，分析了桩与桩间土承担竖向荷载的比例，肯定了高层建筑应用疏桩基础的可能性，其现场实测结果可供高层建筑基础设计及理论研究作参考。 |
| 关 键 词： | 高层建筑 疏桩基础 桩筏基础 现场实测 |

| Abstract: | It puzzles us how to introduce the soil among piles in foundation design for high-rise building. Based on the in-situ measurement on MBA High-Rise Building of Nanjing University, we know some distribution rules of settlement, earth pressure among piles, pressure at pile-top, steel bar’s inner force and the ratio of load bearing by piles and soil among piles; and it is shown that the high-rise building can adopt the sparse pile foundation. These results can be used in foundation design and theoretical research of high-rise building. |
| Keywords: | high-rise building sparse pile foundation pile-raft foundation in-situ measurement |
