| 摘 要： | 盐害腐蚀导致混凝土和钢筋强度衰减,耐久性能劣化。提出用随机过程表达的混凝土与钢筋的抗力衰减模型,推导了基于抗力和荷载为随机过程的井壁时变可靠度功能函数,以此为基础推导出矿井井壁体系可靠度计算可以转化为确定井壁最弱单元可靠度。

| Abstract: | Salt damage corrosion leads to intensity attenuation of concrete and steel,durability deterioration.The resistance degradation models utilized random process which created by concrete and reinforced strength decreased were proposed. The time-dependent reliability performance function was obtained based on viewing resistance and load as random process. Furthermore it was deduced that the computation of shaft lining system reliability can be transferred to compute the most dangerous structure member reliability. |
