连拱坝的工作性态研究
Research on operation behavior of multiple arch dam
连拱坝由于结构单薄，对周围环境变化影响比较敏感。文章结合梅山、佛子岭两座连拱坝的实测资料，采用多种模型和分析方法，对其工作性态进行了对比分析，由此引出连拱坝变形、稳定、强度和裂缝等的不利荷载工况。
The multiple arch dam is sensitively affected by its environment because of its thin structure. Based on the observation data, the operation behaviors of Meishan and Foziling multiple arch dams are comparatively analyzed with many kinds of models and analysis methods. Some unfavorable loading conditions are obtained for the deformation, stability, strength, crack, etc.
