| 摘 要： | 结合港珠澳大桥沉管隧道基础整平工程,采用了多种计算方法分析整平船桩腿在不同地质条件下的插桩和拔桩,得出了自升式抛石整平船桩腿在工作状态下的入土停止层,以及在整平船插腿施工中的抗压极限承载力和桩腿抗拔极限荷载,同时提出在特殊地质条件下的预控措施,并通过工程施工实践验证,证明该分析计算方法是正确的。

| Abstract: | Combined with the Hong Kong Zhuhai Macao Bridge Tunnel Engineering foundation leveling, the calculation methods are put forward to analysis inserting and pulling pile of leveling ship legs in different geological conditions. It is concluded the leg buried layer of self elevating riprapping leveling ship in the work state , and the ultimate bearing capacity and pullout ultimate load of pile legs in the construction of the leveling ship inserting legs. At the same time, pre control measures in the special geological conditions are put forward. The practice proves that the analysis and calculation method is correct. |
