基于未确知测度的混凝土桥梁耐久性综合评估

针对如何在耐久性评估中更为科学的处理信息的不完整和不确定性,本文提出了基于未确知测度模型的在役混凝土桥梁的耐久性评估,并通过实例说明。与其他评估方法相比,发现在不完整信息和多种不确定条件下,未确知综合评判仍能够相对较好的寻找耐久性规律,从而为桥梁的管理及维修加固提供更为科学合理的决策依据。

Synthetical Evaluation Model for the Durability of Concrete Bridge based on Unascertained Measure

For how to deal more rationally with deficiency and uncertainty of information, the model of unascertained measure is used in the durability evaluation of existing concrete bridge and declared by example. Compared with the other theories, unascertained measure can find the rule of durability reasonably under the deficient information and unascertained factors and can supply the more scientific and more reasonable decision foundation for the management and maintenance of the concrete bridge.
