摘　　要：介绍了一种用于桥梁损伤状态评估的有效算法。利用粗糙集在处理不完备信息方面的优势来抽取桥梁构件状态与桥梁安全状态之间的规则。其优点是在对象信息不足或存在冗余时仍然有效而且不需任何先验信息。文章的最后利用两个新样本验证了该算法的有效性。An efficient algorithm is proposed for the damage state assessment of concrete bridges that use rough set as the tool to extract rules as decision method. Take the advantage in processing incomplete information without any preliminary or additional information about data such as probability theory or grade of membership in fuzzy set theory. We use rough set theory to mine rules between the testing data of each branch construction and the state of the bridge. An experiment is done with a given data set, and the result is also analyzed in the loader.
