论述了施工期大坝观测数据混合模型.应用三维有限元方法对坝体结构进行分析计算,综合考虑了坝体在施工过程中水压、温度、时效及浇筑高度、封拱灌浆高度、混凝土水化热对坝体的影响.结合湖北省熊渡重力拱坝实例,建立了熊渡拱坝的混合模型.更加合理地解释、评价大坝工作性态,为大坝安全监控提供了依据 The mixed model of dam observation data during construction period is discussed.The structure of the dam body is analyzed and calculated by using the three-dimensional finite element method. The influences of water pressure, temperature, aging and pouring height, sealing grouting height, concrete water The effect of heat on the dam body.Based on the example of Xiongdu gravity arch dam in Hubei Province, the mixed model of Xiongdu arch dam is established, which can provide a basis for more reasonable explanation and evaluation of dam working behavior for dam safety monitoring
