Evaluation of Hidden Danger of Diseases for Embankment during Operation Time

Pavement damage is usually caused by embankment instability as well as excessive differential settlement. In order to take prompt maintenance for both diseases, a monitoring project should be conducted for those embankment structures with the hidden danger of diseases, which should be identified and evaluated in advance. In this paper, a method of fuzzy evaluation is applied in the evaluation of the hidden danger of both diseases. Evaluating index, membership degree and weight are figured out. An evaluation case is given to validate the method proposed in this paper.
