摘　　要：以某商业住宅楼地下室底板为工程实例,针对实际工程中使用的混凝土材料特性,运用有限元程序对该地下室底板超厚大体积基础筏板混凝土进行水化反应分析,并将分析结果同现场监测数据进行对比。利用有限元模型,具体分析了混凝土浇筑时的表面保温措施对混凝土应力场的影响。根据数值分析结果,对应提出该地下室底板大体积混凝土温控施工技术。Taking the basement floor of a commercial residential building as an example,aiming at the characteristics of concrete materials used in the actual project,the hydration reaction of the concrete of the super thick mass foundation raft of the basement floor is analyzed by using the finite element program,and the analysis results are compared with the field monitoring data.Based on the finite element model,the influence of surface insulation measures on the stress field of concrete is analyzed.According to the results of numerical analysis,the temperature control construction technology of mass concrete for the basement floor is proposed.
