Study Of The Index System Of Assessment For The Maintaining Condition Of Monorail Track Beams And Bridges

The basic task of the maintain of Line 2 of Chungking monorail is to keep the equipments of all the line intact and the quality balanced, so that the trains can move safely, steady and uninterruptedly with rated speed, and the equipments' lives of usage can be extended as long as possible.The main purpose of the assessment for maintaining condition of the track beams and bridges of monorail is to study the changes of their maintaining conditions by analyzing the examine, maintain and manage informations, and the index system of assessment for maintaining conditions of the track beams and bridges is established, by which the transformation of the maintaining mode from' corrective maintenance' to the more scientific and reliable' repairing on condition' which is mostly about' preventive maintenance' would come true.First the author introduces the recent study situation of the bridge condition's assessment, and the usual means of which are describled, the classification of condition of bridges in China and overseas is discussed as well. On the basis of analysing the main problems and their influences of the track beams and bridges, the indexs of the bridge condition's assessment are confirmed, and by processing the values of experts comparative matrixes using the uncertain AHP, groups theory, the principle of set-valued statistics and gravity center based decision theory, the weights of the indexes are calculated. A index system suiting for the assessment for maintaining condition of the track beams and bridges of monorail finally is established, and the process related is computerized as well. It turns out that the index system is viable, simple and convenient, the results reasonable, by a instance.
