Firstly, the key data are obtained from the nomogram, then temperature warp stress coefficient Cx and integration temperature stress coefficient Bx are determined by interpolation. At last, the program is developed by Delphi 7.0 to calculate the board thickness of cement pavement. 首先从诺模图读取关键数据点,然后使用内插方法计算温度翘曲应力系数Cx与综合温度应力系数Bx,以Delphi7.0为开发工具编制相应设计程序,并进行了验算。
