新型防冰护岸结构优化及力学性能分析

Optimal Design and Numerical Simulation of Revetment Structure in Songhua River Main Stream Embankment

松花江每年春季开江形成大量浮冰,导致堤防工程受到不同程度的破坏,严重地甚至穿越堤防。因此,开展松花江干流堤防工程护岸结构优化设计研究是十分必要的。文章针对冰排对堤防结构破坏问题,结合现有冰区护岸结构服役环境特点,提出了一种基于地下连续墙结构的新型半斜坡式护岸结构优化方案,利用ABAQUS软件,开展冰载荷作用下护岸结构的力学性能研究,为季节性冰冻河流新型护岸结构设计及推广应用提供技术参考。

The Songhua River has formed a large amount of ice floes every spring,leading to different degrees of damage to the embankment project,and even crossing the embankment seriously.Therefore,it is very necessary to carry out the research on the optimal design of revetment structure in Songhua River main stream embankment.This paper directed at the problem of embankment structure damage caused by ice floe,combined with the characteristics of the service environment of the existing ice revetment structure,proposed a new semi-slope revetment structure optimization scheme based on the underground continuous wall structure.By using ABAQUS software,the mechanical properties of the revetment structure under ice loading are studied,providing technical references for the design and promotion of new revetment structure for seasonal frozen rivers.
