摘　　要：为避免水泥水化热在基础内积聚导致里表温差过大产生裂缝,论文结合实际,对大体积混凝土筏板基础里表温差及变化规律进行理论模拟,根据模拟结果有针对性地采取水冷降温、温度监测、保温养护等措施,有效控制了混凝土内部温升和里表温差,规避了温度裂缝,验证了理论模拟和温控措施的有效性。To avoid cement hydration heat in base accumulation in table temperature difference is too large and produce cracks,this paper combined with the actual basis in the table temperature difference and change rule theory simulation,according to the simulation results targeted water cooling,temperature monitoring,insulation maintenance,effectively control the concrete internal temperature rise and table temperature difference,avoid the temperature cracks.Through case study,the effectiveness of theoretical simulation and temperature control measures is verified.
