筏板基础大体积混凝土温控抗裂及模拟仿真

Temperature control-anti-crack for raft basal mass concrete and its simulation

对高层建筑筏板基础大体积混凝土施工中的温度裂缝进行了成因分析,并结合温控实例,提出了有效预控温度裂缝的方法,运用有限元模拟其施工中混凝土温度场、应力场的变化规律,说明有限元仿真技术在大体积混凝土温控抗裂中的实用性与可行性。

It analyzes causes of temperature crack in construction of raft basal mass concrete of highorise building, and puts forward prevention measures combined with practical example, then simulates variable rule of temperature field and stress field applying for finite element, which indicates utility ＆ feasibility of simulation.
