摘要
国鸿中心项目塔楼基础区域大体积混凝土结构尺寸庞大,采用一次性整体浇筑方案。在大体积混凝土施工过程中,因水化热导致温度升高和不均匀冷却可能会引发温度裂缝,进而影响混凝土的结构强度和耐久性。结合有限元软件MIDAS/GEN对基础筏板进行温度场与应力场分析,采取温度控制、大体积混凝土测温、温度试验以及蓄水处理等措施,保证了混凝土的质量,取得了良好的效果。
The foundation area of the Guohong Center project tower has a large volume of concrete structure with large dimensions,and a one-time overall pouring scheme is adopted.During the construction of large volume concrete,temperature rise and uneven cooling caused by hydration heat may lead to temperature cracks,which in turn affect the structural strength and durability of the concrete.By combining MIDAS/GEN finite element software to analyze the temperature and stress fields of the foundation raft,measures such as temperature control,temperature measurement of large volume concrete,temperature testing,and water storage treatment were taken to ensure the quality of the concrete and achieve good effect.
