摘要
基于混凝土结构基本理论 ,结合大比尺结构模型试验 ,采用较合理的平均裂缝宽度计算模式和裂缝截面处钢筋应力计算方法 ,建立了新的钢衬钢筋混凝土压力管道裂缝宽度计算方法。算例表明 ,此方法力学概念明确 ,使用方便 ,计算结果与实测值吻合。
Based on the concrete structure theory and combined with large?sized structure model tests, adopting a reasonable calculation mode for mean crack width and steel stresses at crack sections,a new method for calculating maximum crack width of steel?lined reinforced concrete penstock is proposed. The examples show that the concept of this method is clear and employment is convenient, the calculation results are in agreement with test data.
