摘　　要：以浙大创新平台项目中用于倒摆结构的大体积混凝土质量块施工为例,通过采用无垫层大体积混凝土浇筑、模板支撑体系设计、混凝土散热体系设计、混凝土养护及测温等技术,为大体积混凝土施工提供了重要的质量和安全保障,通过冷却管进行大体积混凝土温度控制,有效地解决了混凝土裂缝控制问题,保证大体积混凝土质量块在倒摆结构中能有效地起到消能减振作用。Taking the construction of mass concrete blocks for inverted pendulum structures in the innovation platform project of Zhejiang University as an example,through the use of technologies such as non-cushion mass concrete pouring,formwork support system design,concrete heat dissipation system design,concrete curing and temperature measurement,important quality and safety guarantees are provided for mass concrete construction.The temperature control of mass concrete is achieved through cooling pipes,effectively solving the problem of concrete crack control,ensuring the effective energy dissipation and vibration reduction effect of mass concrete blocks in inverted pendulum structures.
