摘　　要：架空式斜坡码头是我国大水位差(水位差可达20~30 m)山区河流的最主要码头结构形式。因此,在工程设计时,详细分析实例工程的受力情况,保证码头结构的稳定性是工程稳定性的重要前提。以重庆江津区鱼尾碛码头为实例工程,借助三维有限元数值模拟技术,研究了在最不利工况下,实例工程的码头自身结构稳定性及岸坡稳定性。为实例工程的建设提供了稳定性支持依据,也为同类工程的研究计算提供了参考。The aerial slope wharf is the most important wharf structure form of mountain river with large water level difference(water level difference up to 20~30 m)in our country.Therefore,in the engineering design,the detailed analysis of the case project stress situation,to ensure the stability of the wharf structure is an important prerequisite for engineering stability.Taking YuWeiQi wharf in JiangJin district of ChongQing as an example project,this paper studies the structural stability and bank slope stability of the wharf under the most unfavorable working conditions with the aid of three-dimensional finite element numerical simulation technology.It provides the basis of stability support for the construction of an example project and also provides a reference for the research and calculation of similar projects.
