由于施工过程逐层浇注混凝土，自重和温度荷载同时加载，都存在徐变效应。作者提 供了累计温度和自重的徐变应力计算方法和程序，结合碾压混凝土（ＲＣＣ）拱坝工程提供了施工 期仿真应力特点。用简化弹性应力计算施工末期坝体温度下降到运行期坝体稳定变温场受河 床及两岸基础和自身相对变形的约束应力，并和水压应力叠加取得运行期碾压混凝土拱坝仿 真应力，施工期和运行期仿真应力形成最终组合应力。文中提供的混凝土双轴强度判别为应用 仿真应力进行设计提供了条件，仿真计算为碾压混凝土拱坝设计和工程实践提供了可靠依据。
Due to the concrete pouring concrete layer by layer during the construction process, creep effect exists in both self-weight and temperature load loading. The authors provide methods and procedures for calculating creep stress with accumulated temperature and dead weight, and provide simulation stress characteristics during construction with RCC arch dam engineering. The simplified elastic stress is used to calculate the constraint stress of the dam body at the end of construction to the stable temperature field of the dam during operation and the relative stress of the two sides of the riverbed and the foundation and their relative deformations, and the simulation stress of the RCC arch dam during the construction period Simulation stresses during the period and during the run form the final combined stress. The biaxial strength of the concrete provided in this article provides the conditions for the design of the simulation stress. The simulation calculation provides a reliable basis for the design and engineering practice of the RCC arch dam.
