Multiple Linear Regression Method, Stress Field And Its Application Research

Along with the further development of production, stress field engineering rock mass is avery important factor, especially in mining, construction, earthquake prediction and other aspectsof the actual needs. Different geological conditions and rock stress state have different influencedegree to engineering stability. Make full use of limited geostress data by the engineeringmeasurement, use mine enterprises major scientific research projects as the engineeringbackground, funding by the natural science foundation in the high stress conditions rock creepfracture criterion research "(51004007), with the support of the project, diversity line regressionanalysis to carry out in-depth stress field of the inversion method research, obtained the followingmain research results:（1）Established multivariate linear regression stress field mathematical model, improve thestress field inversion analysis method.Through analysis the key factors of stress field, it is concluded that the stress fieldcomposition mainly by the gravity stress and tectonic stress, also concluded that the linearrelationship between the two parts and ground stress. From this the multivariate linear regressionground stress field mathematical model inversion were deduced and established, write multivariatelinear regression stress field inversion process realized based on engineering the stress of themeasuring point ground stress field program to return and inversion, improve the multivariatelinear regression stress field inversion method. Simple and important engineering examples showthe stress field after inversion reliable.（2） Development the visual intelligence operation RSBR system based on VC++platform,Realize the stress field inversion and reconstruction.Combined with the needs of the thesis, in the application of vc++software foundation,according to the actual situation, write related procedure, to implement the visualizationintelligence operation. This method through put several separate operating software focused on abody, and make full use of vc software powerful function, and write automatic operation commandand finally realized this paper multivariate linear regression stress field inversion method of theprocedure. Facts have shown that based on the development of vc++platform, formed theinversion design operate interface, greatly increase the calculation efficiency, simplifiedprocedures, save the time of operation, making it more intelligent, and humanization.Research results show that: in this thesis, the stress field of the inversion method should hasbetter versatility, can be used to mining enterprises to obtain stress field. Therefore,the result of theresearch and achievements for solving the problem of ground stress field of important theoreticalsignificance and practical application value.
