Indicated according to the near two year gauge block anti-curved experiment, when the design intensity takes 435 N/mm2, under the normal running condition the reinforcement stress probably is 343 N/mm2, the corresponding average crack opening approximately in the 0.14~0.15mm scope, if takes 1.66 to multiply the big coefficient, the short-term maximum crack opening reaches 0.24mm, considered the long-term function rides 1.5 to multiply the big coefficient again, final crack opening approximately in 0.36mm.

根据近两年对板的抗弯试验表明，当设计强度取 435 N / mm2，正常使用状态下钢筋应力大约为 343 N / mm2，对应的平均裂缝宽度大约在0.14～0.15mm 范围，如取1.66倍增大系数，短期最大裂缝宽度达 0.24mm ，考虑长期作用再乘1.5倍增大系数，最终裂缝宽度大约在0.36mm 。
