Research Of Stability Intelligent Diagnosis On High Rock Slope Of Building

The analysis on rock slope of building stability is an important work to thegeotechnical engineering in the area of Chongqing. With the expansion of cityconstruction land and the limits of the terrain in Chongqing, more and more peoplebuild house in the surrounding of rock slope, in order to prevent the accident of theslope instability, it is necessary to strengthen the research of rock slope stability.The Chongqing high building slope(consider two kinds of cases: homogeneous andcontains a advantage structure surface which be simplified)is chosen as the researchobject in this paper, this paper simply summarizes all the way of the study of the slopestability and discusses the main factors which influences the slope stability. This kind ofslope is closely related to the human activities, which affects area planning inChongqing, although the scale of rock slope is not big, but the destructive of instabilityis larger; in addition, the failure mechanism of rock slope is not clear cause engineeringof high input and construction of the blind, it is not clear to understand the failuremechanism of rock slope, which cause high input of engineering and the blind of theconstruction, therefore it is necessary to strengthen the stability control of the rock slopein Chongqing. Considering the importance of regional stability of the slope and theslope itself has the "fuzzy" in some ways，it also preliminarily is using the adaptivefuzzy neural theory to establish intelligent diagnosis system in this paper. The mainresearches and conclusions are listed as follows:①According to the analysis of the influence factors on the influence degree of therock slope, choose the key factor which influences slope stability,②Choose the ways of uniform design and strength reduction which bases on thefinite element software ansys to determine the input and output parameters of thetraining sample, choose the anfis module of the matlab software as numerical simulationon the training sample, establish the intelligence assessment system of the stability ofbuilding rock slope.③According to the way of shear strength reduction, the safety factor of everygroups of sample is solved，the general location of the plastic transfixion is found, andaccording to the definition of the broken horn it establishes the effective andpreliminary judge method on the safety of distance of building rock slope, and use thevisual interface environment “Guide” of matlab to design the graphical user interface. As a major part of the achievements of the project topics “Research and applicationof risk intelligent diagnosis technology on high building slope of mountain city urban”by “The construction science and technology plan of Chongqing constructioncommittee” in this paper, which can provide preliminary reference for Chongqingbuilding rock slope stability diagnostic research.
