| 摘 要： | 以嵌岩桩为例，通过进行室内模型试验分析，研究了桩端阻力与桩侧阻力的相互作用。结果表明，桩端岩层对桩侧阻力有较大影响，表现为随着桩端岩石强度的越高，桩侧阻力有增大现象，但这种桩侧阻力的增强效应并不发生在整个桩侧，只集中在桩端附近，反过来，较好的桩侧岩层又可使桩端阻力增大。利用此种相互作用关系可提高桩的承载力，优化桩基设计。

| Abstract: | The interaction between the resistance at pile end and the resistance of pile is researched through the indoor model test on the rock-socketed pile. The result shows that the rock stratum at the pile end influences the lateral resistance of pile; as the increase of strength of rock at the end, the lateral resistance of pile will increase; but the enhancement effect doesn’t occur at the whole side of pile, only near the end of pile. Inversely a good lateral rock stratum also increases the resistance at pile end. The load-bearing capability of pile will be improved by using the interaction relationship so as to optimize the design method of pile. |
