Abstract: Fengtan dam is a vierendeel gravity-arch dam, which has special deformation behavior. Based on the theory of the temporal-spatial displacement model, a line of the deflection model is established to analyze the deformation rule of the radial displacement of the dam. The result is satisfied.

摘要: 凤滩大坝为混凝土空腹重力拱坝,变形性态有其特殊性。本文利用位移时空监测模型的基本原理,建立了凤滩空腹重力拱坝的挠曲线模型,并应用其分析了坝体径向位移的变形规律,取得了令人满意的效果。
