以实际工程为例，对现浇楼板跨中产牛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。
以實際工程為例，對現澆樓闆跨中產牛的溫度收縮裂縫進行瞭調查研究，結閤溫度收縮應力計算、應力集中分析，從理論上驗證闆中預埋線管處應力的集中，引起跼部溫度收縮應力過大，誘髮產生溫度收縮裂縫的現象，為今後的樓闆裂縫控製提供瞭有益的參攷。

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.
