摘要

以软土地基上的海堤为研究对象，根据软土变形的时效特征和自重应力场与渗流场的耦合特性，建立了软土蠕变模型和渗流作用下的耦合应力场分析模型，将堤身、堤基作为整体进行了变形特性分析。并采用强度折减有限元法分析了海堤在自重、波浪力和渗透力耦合作用下的整体稳定性。分析结果表明：软基海堤结构处于多种荷载效应的综合作用之下，不仅对堤基和堤身断面的位移场和应力场影响较大，而且对其整体稳定性也有很大影响。通过计算值与实测值的对比，证明了所建计算模型和所采用的计算方法的正确和适用，所得结果具有理论意义和实用价值。

Abstract

In light of the stability of coastal levee on soft foundation

according to the time-dependent properties of soft soil and the coupling properties of seepage field and stress field

creep model of soft soil and analytical model of coupling stress field are established; and the deformation properties are analyzed by taking the coastal levee and its foundation as a whole. The overall stability under the coupling force of dead-weight

wave force and seepage force is analyzed by the shear strength reduction with FEM. Results show that the coastal levee structure under the comprehensive functions of many effects

not only there are more impact on displacement field and stress field of foundation and section

but also the overall stability. The validity of the model and computing technology is proved by compared with the measured data; and the conclusions obtained in this paper have theoretical meaning and practical value.
