大体积混凝土温度裂缝在实际工程中的控制技术

Technique for Controlling Temperature Crack on Mass Concrete in Practical Project

大体积混凝土的裂缝控制是一项较复杂的课题,理论与实践经常存在一定的偏差。结合山东济南的一个大体积混凝土施工实例,施工前用有限元分析模拟大体积混凝土温度场,根据分析结果制定施工方案,就实施结果总结出裂缝控制的施工经验。

The control of crack in the mass concrete is very complex because a cerrtain distance exists between theory and practice. This article incorporates with an example of mass concrete construction in ShanDong Jinan, anslysises an simulates the temperature field of the mass concrete by the finite element method before constructing and makes a project according of the result. Based the result, some experience is given for reference for some similar projects.
