摘要

提出了用新型套管桩基来提高海洋平台桩基水平承载力和减小平台响应幅值。采用p-y曲线法来模拟桩土间的相互作用，对套管桩基进行非线性响应分析，研究了套管的埋深和宽度对桩身变形和土抗力的影响，并与普通桩基进行了对比分析。研究表明，套管桩基能充分发挥桩土间的相互作用，提高桩基的水平承载力，减小桩基的水平响应。

Abstract

A new type of casing pipe pile foundation is presented to increase the offshore pile foundation lateral capacity or decrease the lateral displacement. The nonlinear response of the casing pile under lateral load is studied by means of p-y curves. The influence to the pile response of the depth below the seafloor and the width of the casing pipe is investigated and compared with the common pile. The results show that the casing pipe can excite the pile-soil interaction effectively and increase the pile foundation capacity and decrease its response to lateral loads.
