摘要
钢筋混凝土抗滑桩必须进行裂缝控制,这与保证足够强度一样重要。抗滑桩属受弯构件,为了使《混凝土结构设计规范》(GB 50010—2010)裂缝宽度计算公式适用于圆截面均匀配筋受弯构件,在分析公式的各个相关因素之后,通过调整它的系数和修改它的参数(σs,ψ,ρte),得出了圆截面均匀配筋受弯构件的裂缝宽度计算公式,构建了一个函数表以简化计算过程。实例的裂缝宽度计算结果表明,建议的方法是简便、合理和可行的。
The crack of reinforced concrete anti-sliding piles must be controlled, which is important as well as strength assurance. Anti-sliding piles are flexural elements. In order to make the crack-width formula in Code for design of concrete structures（GB 50010--2010） be applied to crack control of reinforced concrete flexural elements with circular section for uniform reinforcing, after analyzing its each relative factors, the crack-width formula of flexural elements with circular section for uniform reinforcing was presented by adjusting its coefficient and modifying its parameters （σs,ψ,ρte）. The function table for simplifying calculation was also given. The result of crack width calculated in the practical examples shows that the advised method is simple, reasonable and feasible.
