摘要
工程上钢筋混凝土压力管道表面通常会出现裂缝,传统钢筋混凝土压力管道的抗裂计算是建立在连续体的假设基础上的.现以假设构件在开裂前存在宏观表面裂缝为基础,抗裂度定义为抵抗发生穿透裂缝进而引起裂缝失稳扩展,基于断裂力学理论对钢筋混凝土压力管道的断裂分析进行了初步探讨.
There is crack usually in the surface of reinforced concrete pressure conduit engineering. Traditional fracture calculation of reinforced concrete pressure conduit is based on the assumption of continuum. This paper is based on the assumption of member existing macroscopical surface crack before fracture and anti-fracture degree is defined resisting occur penetrant crack and lose the stabilization and propagating. The author initially studies reinforced concrete pressure conduit according to fracture mechanics.
