Research On Comprehensive Evaluation For Exceptional Dimension Freight Safety

With the reform and opening policy, China's national economy has entered a new period of development, all the country is to seize the good opportunities to develop market economy, so that a lot of national construction materials swarm into railway market. Especially in these years, with the rapid development of construction of the emphasis engineering an national defence in our country, more and more oversize engineering equipment were transported by railway. Owing to the characters of oversize, out-of-gauge and overweight, these goods need the special transport organization plan in good loading, reinforce and transport.It has a grave effect on the railway transportation safyty, so research on the related problems of the transportation safyty for these goods have significant meaning of theory and practice.Railway exceptional dimension freight transportation is the work that needs high technique. There are lots of factors that affect railway exceptional dimension freight transportation. In order to comprehensively evaluate railway exceptional dimension freight transportation safety, the characteristics and objective analysis must be considered completely and systematically.Based on the the theory of exceptional dimension freight and railway transport organizations, this article analyse the influencing factors of exceptional dimension freight transportation. And combining concept, purpose, contents, procedure of safety evaluation and the principle of safe evaluation should be followed, evaluating a method to the safety and it choose to use to carry on analysis and study. Based on checking a great deal of data, build up a comprehensive evaluation indicators system of exceptional dimension freight transportation safety after asking for the experts' opinion for many times. Apply several comprehensive evaluation models to evaluate the loading and reinforcing plan, railway conditions, and management level of the exceptional dimension freight tranportation, carried on an expert to inquire, passed an analytical calculation to make sure the power heavy coefficient of each index sign, with an example was given.It can provide the effective reference for the railway enterprise to make decision of the exceptional dimension freight transportation.
