通过对秦沈客运专线六股河大桥第 3 8孔箱形梁的水化热温度和温度应变适时观测数据的统计与分析 ,研究箱梁水化热阶段的温度尤其是温度应变的变化规律 ,为研究水化热阶段的温差应力及相应的早期裂缝控制提供参考依据
Based on the statistics and analysis of the timely observation data of the hydration temperature and strain of the third 8-hole box girder of the Qinhuangdao-Shenyang Passenger Dedicated Line, the variation law of the temperature, especially the temperature strain of the box girder hydration stage is studied. Hydrothermal stage of temperature stress and the corresponding early crack control provide a reference
