在建造边缘码头时，桩通常安装在倾斜的填石中。虽然有很多关于倾斜砂、粉土和粘土剖面中桩的横向性能的信息，但关于倾斜或水平填石中桩的横向性能的信息有限。本文总结了最近的研究成果，使用离心机和数值模型，以及现场数据，以更好地了解桩的性能在边缘码头。结果表明，修改目前的分析方法，需要准确地模拟桩在倾斜的岩石填充的横向行为。需要进行修改，以考虑倾斜剖面，导致下坡方向的p-y曲线极限强度降低。此外，如果填石的直径与桩的直径大致相同，则需要增加上坡和下坡方向上的p-y曲线的极限强度，以考虑桩与填石之间的离散颗粒相互作用。
Piles are often installed in sloping rock fill for the construction of marginal wharves. Though much information is available on the lateral performance of piles in sloping sand, silt, and clay profiles, only limited information is available on the lateral performance of piles in sloping or horizontal rock fill. This paper summarizes the results of a recent research effort using centrifuge and numerical models, as well as field data, to better understand the performance of piles at marginal wharves. The results indicate that modifications to current analysis methods are required to accurately model the lateral behavior of piles in sloping rock fill. Modifications are required to account for the sloping profile, resulting in reduced p-y curve ultimate strength in the downslope direction. In addition, if the diameter of the rock fill is approximately the same as the pile diameter, the ultimate strength of the p-y curve in both the upslope and downslope directions needs to be increased to account for the discrete particle interaction between the piles and rock fill.
