分析了用现有计算公式计算钢衬钢筋混凝土压力管道裂缝宽度的计算值与实测值的符合程度 ,建立了精确度较高的计算钢衬钢筋混凝土压力管道裂缝宽度的半理论半经验公式
The calculated half-theoretical half-empirical formula for calculating the crack width of steel-lined reinforced concrete pressure pipe is established based on the calculated coincidence between the calculated value and the measured value of the crack width of the steel lined reinforced concrete pressure pipe by using the existing calculation formula
