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。
On the basis of the reliability identification of existing concrete structures, stochastic process models of concrete carbonation depth and component bearing capacity and service life are established respectively based on the measured data, and the residual service life of concrete structures is obtained quantitatively under actual operating conditions. A more scientific method is provided for predicting the remaining useful life of existing concrete structures for reference in assessing the durability of concrete structures.
