近海松软沉积物运动对桥梁桩基础的影响分析

摘要

针对松软沉积物在外荷载作用下的移动对跨海大桥桩基础产生的影响进行了研究，确定了沉积物移动荷载及合理的桥梁基础的受力参数，并提出桩基础受力的模式，以期对桥梁桩基础的设计与计算提出有效建议。%The paper studies the influence of the movement of the softy sediments under the external loading effect on the pile foundation of cross sea bridge, identifies the movement loading of the sediments and the reasonable stressed parameter of the bridge foundation, and points out the stressed model for the pile foundation, so as to point out some effective suggestions for the design and calculation of the pile foundation of bridges.
