New dam safety evaluation tool:Enhanced inspection and monitoring through potential failure mode analysis;

In order to get the cause of a bridge s damage,several detection methods are used:Based on the appearance observation,firstly,ultrasonicrecovery synthetical method and supersonic flaw detecting are used to progress microcosmic detection;secondly,using structural strength theory,we got its mechanics analysis;in the end,the causes of the bridge s damage are analyzed synthetically.
