Application Of Fuzzy Theory And Gray Systematic Theoryin The Embankment Bank Slope Stability Analyzing

The urban embankment project plays a quite important role in the social development, it is one of themajor disasters commonly met in the construction of the embankment that lost its stability. A large amountof subjective and objective uncertainty exist in Traditional analyzing methods. Fully considering uncertaintycaused by various kinds of factors is the development trend in slope stability study.This thesis first mainly introduces the present stability of slope computation several kind of commonlyused simplifications limits zero-method principle and the serviceability and points out several uncertaintyanalyses method the deficiency. Regarding the embankment bank slope as a fuzzy-gray system system, weintroduce the correlation theory basic concept, the theory and the computational method in detail.Application of gray systematic theory in the stability studying of embankment bank slope juststarted. For the first time, This thesis uses the gray correlation analytical method, multi-attributesmulti-level language operator GIOWA in the analysis influence bank slope stable factor andmake a unfit quality arrangement of all kind of affected the factors. It indecades various factors theinfluence, so that we can used in the engineering design.This article introduces the fuzzy - gray connection analysis principle and the method and makes thesynthesis analogy assessment in Nanning. Take some embankment bank of Nanning as the example anddivides 4 kind of destructions forms has made the fuzzy-gray correlation analysis separately in 12influences factors. Discovered somt best factors to each kind of corresponding destruction form. so we canreference in later project governmentThe result of study shows: application of fuzzy system theory and gray systematic theory in the urbanembankment project is appropriate, practical and effective, and have a good prospect. The fuzzymulti-attributes multi-level generalized analysis to the urban embankment project is appropriate moreoverpractical and can fast and accurate carries on the appraisal to the urban embankment project.Fuzzy system theory and Grey correlation factor analysis have actual project meaning in guiding measuresmade to instruction; Using Fuzzy-Gray synthesis analogy the method to aim at the different destruction and different factor to make correlation analogy separately and discovers some factors for the fastdiagnosis of the urban embankment and provide one new method for. the Preventing and controlling.
