不同因素对大体积混凝土温度场的影响及模板选择标准

Different Factors on Mass Concrete Temperature Field and Template Selection Criteria

通过对某工程大体积混凝土梁的研究,介绍不同环境温度、不同模板材料、不同截面尺寸对温度场的影响,分析了大体积混凝土温度场的变化规律,提出了大体积混凝土模板选择的标准及建议值,为实际工程的应用提供了选择依据,保证大体积混凝土强度能够均衡、较快发展。

Through the research of large volume concrete beam in a project,different influencing factors of the mass concrete component temperature field are introduced,such as different temperature,different template materials,different section dimensions.Moreover,temperature field change rule on the mass concrete is analyzed,and the selection criteria and recommended values of the mass concrete template are proposed,which provides the choice basis for practical engineering applications,guarantees that the strength of mass concrete could be equilibrium and has faster development.
