潮位变化对高桩码头桩基承载能力的影响

Influence of tide variation on pile foundation bearing capacity of high-piled wharf

根据有效应力原理,以潮位上升引起土层有效应力减小,导致桩基承载能力降低,解释高桩码头单桩竖向静载荷试验过程中,桩顶沉降随潮位上升而持续增加,难以稳定的现象,并对受潮位影响的桩基设计提出合理建议。

Based on the principle of effective stress, the decrease of soil effective stress caused by the rising tide, resulting in reduced the bearing capacity of pile, which can explain the phenomena that the settlements of pile top had risen steadily and stabilized difficulty during the vertical static load test of single pile, and the sensible suggestions are put forward to the design of piles influenced by tide.
