摘　　要：针对凤滩空腹重力拱坝坝顶切向位移变化规律与拱坝常规变形规律的不同,从物理、力学角度出发分析其可能的原因,构建了空间挠度模型,据此分析该坝的变形规律,评价大坝的工作性态。According to the analysis of the monitoring data, the abnormal tangential displacement behavior of the crest of Fengtan vierendeel gra vity-arch dam has been discovered.In connection with this problem, firstly acco rding to the physical and mechanical knowledge the probable reasons are consider ed. Then the analysis of statistical model is carried out to analyse the deforma tion behavior and evaluate the working condition of the dam.
