摘　　要：以实际工程为例,对现浇楼板跨中产生的温度收缩裂缝进行了调查研究,结合温度收缩应力计算、应力集中分析,从理论上验证板中预埋线管处应力的集中,引起局部温度收缩应力过大,诱发产生温度收缩裂缝的现象,为今后的楼板裂缝控制提供了有益的参考。This paper took practical engineering as an example, studied the temperature-shrinkage crack of cast-in-place reinforced concrete slabs, and verified the appearance of temperature-shrinkage crack caused by stress concentration in the pre-embedded pipe by calculating the temperature-shrinkage stress and analyzing the stress concentration. These conclusions are useful to the crack control of the slabs.

关 键 词：混凝土楼板 温度收缩应力 裂缝 应力集中
