摘　　要：拱坝对坝址基岩强度要求较高,在基岩软岩夹层发育或地质条件复杂区域,需重点对拱坝的应力变形进行分析研究。文章结合某双曲拱坝,建立数值模型计算坝体及坝基应力、坝基变形对拱坝应力及稳定的影响,分析不同封拱温度、封拱顺序对拱坝应力及稳定的影响,提出最优封拱温度和封拱顺序,优化温控设计及措施。Arch dam requires higher strength of foundation rock,the stress and deformation of arch dam should be analyzed and studied in bedrock soft rock interlayer development or geological conditions complex area.Combined with a double-curved arch dam,in this paper,a numerical model was established to calculate the stress and stability of the dam body and foundation,to analyze the influence of different sealing temperature and sealing sequence on stress and stability of arch dam,and pptimal arch sealing temperature and sequence were put forward to optimize temperature control design and measures.
