摘要

沉井加桩复合基础是一种结合沉井及群桩各自优点形成的新型跨江海桥梁深水基础型式。在复杂的江海环境下

基础将承受强风、波浪及地震等引起的水平动荷载作用

其水平动力特性研究是复合基础合理设计施工和推广应用的重要保证。基于动力Winkler模型分别提出了沉井加桩基础的频域非线性及时域非线性计算方法

并同有限元对比验证了简化方法的正确性。通过算例进一步分析了冲刷对沉井加桩基础动力特性的影响规律

结果表明

土体应力历史及土体非线性对复合基础动力阻抗、共振幅值及频率均有显著影响。

Abstract

Caisson-piles foundation（CCPF）

which combines the advantages of caisson and pile groups

is a new type of deep water foundation for bridge crossing rivers or seas.CCPF is usually subjected to horizontal loads and moments caused by wind

ocean wave or earthquake due to the complicated marine environment.Research on lateral dynamic characteristics of CCPF has become the important guarantee for rational design and engineering application of this foundation.Based on the dynamic Winkler model

nonlinear analysis methods in the frequency domain and time domain for CCPF were proposed respectively.The reliability of the simplified methods was validated by comparing with the results from finite element simulations.Then

the scour effect on lateral vibration of CCPF was also analyzed.The results show that stress history and nonlinear characteristics of soil have significant influence on dynamic impedance

resonant amplitude and resonant frequency of CCPF.
