Study on Cluster Analysis of Approach Degree of Fuzzy Matter-Element for Soil Corrosity along Gas Pipeline

In this paper, on the basis of fuzzy matter-element analysis combined with the concept of approach degree, a method of cluster analysis of approach degree of fuzzy matter-element is provided for the evaluation of soil corrosity along gas pipeline and the evaluation model and the classification standard are built. An example shows that the result is coincided with other methods and corresponded to practices. This method may be referred for the related technicians.
