摘要

在港口桥梁工程和海洋工程中，一般将桩从桩-土-承台结构中分离出来，单独计算波浪力对桩的作用。在提出波浪力作用下桩-土-承台结构相互作用模型的基础上，结合工程算例，进行了桩-土-承台结构在波浪力作用下桩的荷载和弯矩计算分析，结果表明：在不考虑波浪力的情况下，计算结果跟规范方法较为接近，验证了桩-土相互作用模型的适用性。在此基础上迭加波浪力，将波浪力和桩-土-承台作为一个完整的系统研究，随着承台所受外力、波浪力、桩侧地基土的变化，分析了桩-土-承台结构在波浪力作用下的受力效应。

Abstract

Generally

the action of wave forces to piles is calculated separately by dissociating piles from the structure of piles

soils and base slabs (PSBS) in harbor

bridge and ocean engineering. Based on the interactive model of PSBS that we put forward before[1]

we conduct a calculation and an analysis of piles loads and bending moments of PSBS under wave loads by combing an engineering example. The result shows that the calculated results by the interaction model are very close to the results by the criterion method with no wave force. Thus

the applicability of the interaction model is test and verified. And then

we considering a whole system that composes of wave load and PSBS by adding the wave loads

analyze its mechanical effects of the PSBS under wave loads with the changes of external load

wave load and the coefficient of soils around a pile of a base slab.
