摘　　要：江边水电站拦河闸坝最大高度27.5 m,基础座落在109 m深的覆盖层上,闸坝基础变形问题是工程的关键技术问题。采取有效工程处理措施,努力减小坝体沉降和控制坝体不均沉降,是工程建设成败的关键。本工程采用基于Biot固结理论的有效应力方法进行三维有限元静力分析,计算坝体沉降变形。本文通过闸坝实测变形成果与三维有限元静力分析计算成果对比分析,对基础覆盖层变形计算方法、计算理论进行分析与评价。The maximum height of gate dam is 27.5m and the dam base is located on overburden layer with 109m depth for the Jiangbian hydropower station.The deformation of the gate dam base is the key technical problem of the project.Taking effective treatments to decrease settlement and control differential settlement of dam body is the key point of the project success construction.By using the effective stress method based on the Biot consolidation theory,the paper analyzes the three-dimensional finite element static and calculates the settlement and deformation of the dam body.Comparing between the measured deformation values in site and the threedi mensional finite element static calculation results,the paper analyzes and evaluates the calculation method and theory for the deformation of the basic overburden layer.
