摘要

为了探究砌体冻融耐久性寿命,以强度损失率为损伤指标建立砌体材料冻融损伤的耐久性模型,计算耐久性损伤可靠指标.通过可靠指标划分砌体材料的冻融损伤耐久性等级,计算得到各等级先验耐久性寿命预测曲线,结合检测信息通过贝叶斯方法更新预测曲线.结果表明,后验预测模型结合了先验信息和检测信息,预测结果合理.

Abstract

In order to explore the freeze-thaw durability life of masonry,a durability model of freeze-thaw damage of masonry materials was established with the strength loss rate as the damage index,the reliability index of durability damage was calculated.The freeze-thaw damage durability grade of masonry materials was divided by reliable indicators,and the prior durability life prediction curves of each grade were calculated,and the prediction curves were updated by Bayesian method based on the detection information.The results show that the posterior prediction model combines the prior information and the detection information,and the prediction results are reasonable.
