| 摘 要： | 桩筏基础的竖向受力工作性状与刚性桩复合地基相似.尝试采用刚性桩复合地基有关理论及计算模式来分析桩筏基础的沉降变形工作状态.结果表明,采用刚性桩复合地基的应力扩散法比复合地基"规范法"预测变形精度更高;规范法计算复合模量的方法存在不足.

| Abstract: | The working mechanism of pile-supported raft foundation under vertical load is similar to rigid-pile composite foundation, therefore, the methodology of composite foundation is applied to pile-supported raft foundation. It shows that the calculation results derived from the rigid-pile stress divergence approach is more precise than that of National Code Approach; and the National Code Approach is defective in calculating the composite modulus by attempted to use the theory and calculation method of rigid-pile composite foundation. |
