| Abstract: | A math's model of fuzzy comprehensive evaluation is used to divide the degrees of risk of gob collapse at Mencheng town. Eleven evaluating factors are chosen which influence the risk degrees of gob collapse mostly, these factors are divided into three classifications, which are geology, exploitation and the characteristic of land. Using the two-stage fuzzy comprehensive evaluation, the risk degrees of ground collapse at Mencheng town are divided into three classifications, that is, risk zone, relative risk zone and relative stability zone. The evaluating results can reflect the facts better, and can provide a scientific basis for the disaster control and the city planning. |
| Keywords: | gob collapse division of risk degree fuzzy comprehensive evaluation |
