| 摘 要： | 以荷载传递法、有限单元法和弹性理论法的混合解法为基础进行桩筏基础体系分析。深入研究桩筏基础在桩基发生沉降过程中基底土反力和底板内力的变化规律，合理计算桩筏基础地基土荷载分担比，并提出基础底板设计中荷载取值的原则，为多层及小高层地下室底板设计提供依据。

| Abstract: | An hybrid approach for pile-raft system, in load-transfer function, finite element analysis, elastic theory, the paper further studies that the responses of pile-raft foundation average settlement, soil reaction distributing and raft internal force. Soil reaction being computed accurately is the premise of raft design reasonably. Some interesting conclusions above, which may be useful for application of pile-raft foundation and revision of criterion, are obtained. |
