| 摘 要： | 通过对挤扩多盘桩现阶段的理论研究与实际工程对照，初步探讨了当承力盘处于不同性状土层及土层厚度不同时对承载力及土体破坏状态的影响，将进一步完善不同情况下挤扩多盘桩单桩极限抗压、抗拔承载力的计算模式和上体的破坏机理，为进一步保证挤扩多盘桩设计的合理性、可靠性及实际工程的可应用性提供了初步的根据。

| Abstract: | Contrasted with present theoretical study of the Push-extend Multi-under-reamed pile and practical engineering, preliminary discussed the affect of bearing capacity and collapse state of soil when bearing plate is in soil of different properties and different soil thickness. It will improve the calculation mode of ultimate compressive and uplift bearing capacity of that single pile and the destruction mechanism of soil in different conditions. It will also guaranteed the rationality, reliability and application of practical engineering of the Push-extend Multi-under-reamed pile. |
