混凝土结构耐久性的修复性等级划分

采用修复费用、修复工作量、修复时间、可靠性、适修性、恢复性和环境属性7个指标，将混凝土结构耐久性修复等级划分为特修、大修1、大修2、中修1、中修2、小修1与小修2共7个等级，给出了各个等级的指标值。同时，应用模糊控制理论，建立了修复等级模糊划分的数学模型，以7个考核指标作为输入量对修复等级进行综合评判。该模型可在计算机上操作，具有一定的实用价值。

Restorability class partition for durability of concrete structure

In terms of seven indexes,restorability cost,restorability work amount,restorability time,reliability,restore-suitability,restoring degree,and environmental nature,restorability class is partitioned into seven ones that are special restoration,heavy restoration-1,heavy restoration-2,medium restoration-1,medium restoration-2,current restoration-1,and current restoration-2.And the ranges of seven indexes according with seven classes are suggested.Meanwhile,the fuzzy-control theory is adopted to evaluate the restorability class of concrete structure,which takes the above seven indexes as input vectors.The mathematical model of fuzzy partition for restorability class is established,which has applying value because of operability in computer.
