Research On Muddy Interlayer Clustering Method Based On Meso-structure Characteristics

As we known,muddied intercalation is one of the important factors that lead to slope instability,grasp the mechanical properties change rule of muddied intercalation can essentially reveal the instability mechanism of the slope which contain muddied intercalation.From the mesoscopic level, in geotechnical engineering,the mechanical properties of rock and soil is closely related to their mesoscopic structural characteristics,grasp the mesoscopic structural characteristics of the muddied intercalation can accurately describe the mud layer mechanical properties,so as to provide technical guidance in the slope engineering which contain muddied intercalation.However,because of its special form,normal laboratory test is difficult to accurately describe the structure form of the muddied intercalation,so the evaluation of its engineering properties are often relying on subjective judgement,and leads to a big human factors in evaluation results,the application value in the slope engineering is not high.In view of this,this thesis based on the key structural parameters which control the mechanical properties of the muddied intercalation,by building similarity model between the mean structural parameters in muddied intercalation,combining with similarity clustering criterion,established a clustering method based on structural characteristics of the muddied intercalation,provided the necessary guidance for micromechanics performance analysis of the muddied intercalation,it also provides a technical reference for the clustering research on other complex materials.This thesis mainly do the following several research:K By using scanning test,combining image processing technology with image processing software,did a quantitative analysis for structural characteristics of the muddied intercalation under the high magnification,acquired the different distribution characteristics of structural parameter between different microstructure of the muddied intercalation,provided a data support for subsequent similarity calculation model.2> Through mathematical statistical analysis,Combined with the similarity theory,established a set of similarity calculation model which suitable for the characteristics of the muddied intercalation structure.Acquired the similarity degree between different structural parameters of the muddied intercalation,provided a theoretical basis for similarity evaluation between muddied intercalation structure.3, Combining with image fusion technology,by choosing reconstructed image which is the most close to the real porosity,acquired typical image that covered structural characteristics of the muddied intercalation,provides the necessary basic premise for the establishment of structural mechanics model of the muddied intercalation.Constructed a general idea of " Structure parameters quantification?SStructure parameters clustering? Structure characteristics reconstruction" research on muddied intercalation structure.provided the necessary premise for subsequent analysis of the mechanical properties for muddied intercalation,also provided a technical reference for the clustering methods research on other complex materials.4^ Combined with practical engineering,verified the clustering methods for muddied intercalation which put forward by this thesis is feasible.Differences in the form of the structure directly affects its mechanical properties,the clustering method that start from the differences of structural characteristics of muddied intercalation can directly represent the most of the difference of its mechanical properties,clustering results have higher engineering application value.The purpose of this thesis is to provide a set of clustering method based on the mudded interlayer structure,both provide necessary basis for mechanical properties research on muddied intercalation, also provides the technology reference of the structural clustering research on other complex materials.
