摘　　要：针对大型工程泄水孔的上、下游牛腿施工期应力复杂、配筋计算方法不明确等难题,利用大型通用程序ANSYS对底坡比为1∶1、悬挑长度和高度均为27 m、每层浇筑厚度为3 m的牛腿进行了施工浇筑期有限元计算。计算结果能够较好地反映施工期牛腿各个浇筑层之间的应力变化情况,从而可以进行合理的配筋设计。The corbel with 1：1 base stop ratio, 27 m of overhang height and length and 3 m of pouring thickness each layer during the construction period was calculated by ANSYS which is a general finite element program, which aimed at the problems in the upstream and downstream corbel of orifice for large-scale projects such as complex stress of construction period, uncertain calculation method for reinforcement and so on. The calculated results can well reflect the stress variation of various pouring layers in the corbel during the construction period, thereby reinforcement design is reasonable.
