【摘要】 在现有混凝土结构可靠性鉴定的基础上 ,依据实测数据分别建立了混凝土碳化深度和构件承载能力与使用年限的随机过程模型 ,定量地得到了在实际运行工况下的混凝土结构剩余使用年限 ,为现有混凝土结构剩余使用年限的预测提供了一条更为科学的方法 ,可供有关混凝土结构耐久性评估工作参考。更多还原

【Abstract】 In the paper, models of random processes for the depth of the concrete carbonation, the bearing capacity of the members and the service life are established respectively acorrding to the practical problem,and on the basis of the reliability appraisal of the existing concrete structure. The surplus service life of the concrete structure is determined quantitatively on condition of practical operation. A more scientific method is provided for the calculation of the service life of the existing concrete structure,which provides a reference for the appraisal of the endurance of some concrete structures.更多还原
