| 摘 要： | 根据钢管桩轴向受荷承载力机理,从钢管桩的桩土特性、入岩深度、桩土恢复系数及沉桩工艺方面分析了开口钢管桩承载力的影响因素,提出在特定桩型、桩径情况下,桩的入岩深度及闭塞效应是影响桩承载力的重要因素,可通过改进沉桩工艺加深钢管桩入岩深度来提高桩承载力。

| Abstract: | According to the interaction mechanical property of open- ended pile and soil, the influencial factors of bearing capacity of steel pipe pile are analyzed by stiffness ratio of pile to soil, pile embedment depth, soil recover coefficient and construction technology. It can be concluded that the embedment depth in rock and plugging up effect of open- ended pile affect the bearing capacity mostly with specific pile radius, and it needs modifying the construction technologytoincrease embedment depth ofopen- ended pile toenhance the bearingcapacity. |
