结合某无粘结预应力钢筋混凝土板施工实例，利用midas软件对该板分别在2月份、5月份、8月份、11月份施工时，由水化热、环境温度变化等引起的混凝土板内部应力情况进行了模拟，并依据模拟得到的应力分析了板的开裂情况，最后提出了一些预防钢筋混凝土板产生裂缝的可操作性方法。%Combining with the construction examples of some non-bonded prestressed reinforced concrete,the paper adopts midas software to sim-ulate the internal stress of the concrete plates caused by the hydration heat and environment temperature changes in February,May,August and November,analyzes the cracks in the stressed analysis in the simulation,and points out some operable method to prevent the cracks on the rein-forced concrete plates.
