摘要

针对一工程发生破坏的实例，对软土地基条件下大型圆筒海岸结构的设计与计算方法进行了比较分析，并对波浪水流作用下软土特性参数的选取、泥面冲刷对结构稳定性的影响等进行了讨论。提出了反复荷载作用下软土的动力特性、水流作用下结构周围泥面的冲刷演变规律以及波浪作用下大型圆筒结构与软土的动力相互作用等，这都是软土地基条件下大型圆筒海岸结构工程应用亟待解决的关键问题。

Abstract

In the light of a failure project

the stability calculation methods for large cylinder structures in coastal soft clay foundation are compared

and the determination of design values of soft clay in the wave action and effects of foundation scour on the stability of large cylinder structures are discussed. It is shown that the stability calculation methods of the traditional gravity structures are unsuitable for (can not be used in) the stability analysis of the large cylinder structures in soft soil foundation. It is proposed that the dynamic behavior of soft clay in the action of circle load

the evolution of foundation in fluid scouring and dynamic interaction simulation of large cylinder structures and soft clay under the wave excitation should be the key problems to be solved in the practical application of large cylinder structures in coastal soft clay foundation.
