Interval Analysis Applied And Studied In Landslide Hazard And Risk Assessment

Recent years, internal analysis is applied in practical works as a solution of uncertainty with the appearing of internal mathematics. In respond to the needless of subjective information in internal analysis, as just the upside and downside of parameters, the internal analysis method is getting its prospect. The thesis makes the calculating formula of limit equilibrium method in internal form via relating internal analysis method and slope rigidity limit equilibrium method, and then being applied in practice.Main works an result of thesis followed:(1)Introducing the merit and disadvantage in dealing with uncertainty with internal analysis; Emphasizing internal expanding problems in internal mathematics and some solutions; Making a decision of choosing the best suitable method via comparing all the solutions.(2)Taking slope rigidity limit equilibrium method and internal analysis to link together, then making the formula of internal limit equilibrium, mainly including Sweden piece-depart method, Bishop method, residual thrust method. Making the analysis of present Tie Shen Gou slope as a keystone, using the three internal analysing methods to calculate the stable safe factor intern. Then comparing the three methods and summarizing the diversity.(3)Contacting the typical method of landslide hazard and risk assessment, assessing the Tie Shen Gou landslide with typical hazard and risk. And then discussing the assessment formula.
