基于软岩下回采巷道全程变形规律的研究

s the roadway surrounding rock rheological properties, control and prediction of soft rock roadway deformation law for the roadway and the roadway safety during service becomes very important. In this paper, multi-stage loading under uniaxial rheological tests, theoretical analysis and field monitoring results, the use of genetic algorithms, to select and determine a reasonable rheological models and parameters and to establish a roadway surrounding rock rheology models, identify roadway Evolution of the size of the resulting displacement, combined with on-site monitoring, the final accuracy to be soft rock roadway length of service in different deformation of the whole process.
