摘　　要：以万家口子拱坝河床处4号坝体为研究对象,采用三维瞬态有限元法分析新老混凝土结合面部位的温度应力,提出新老混凝土结合面的配筋建议,以保证大坝结构的稳定可靠。The combination strength of old-new concrete interface is generally lower than that of integral casting concrete, which greatly affects the reliability of the structure. It is known that temperature stress is a major factor damaging the combination strength of old-new concrete interface of arch dam. In this paper, the No. 4 dam section at the riverbed of Wanjiakouzi arch dam is taken as an example to analyze the temperature stress on the oldnew concrete interface through three-dimensional transient finite element method, and suggestions are provided for reinforcement design of the interface.
