Analysis and control on stability of surrounding rock with high ground stress

Based on the comparative analysis of the differences between measured values and calculated values,it is proposed that the marked calculated values will deviate in the post-peak deformation stage. Based on the comparative analysis of cracking process between engineering surrounding rock and experimental specimens,it is proposed that the constitution relation experiment of rock will distort in the post peak stage. Based on the analysis of rock mechanics development,compare with the first distortion of rock mechanics experiment,the second distortion of rock mechanics experiment is proposed. Based on the analysis of interaction between surrounding rock with large deformation and the supporting structure,the main reason for the current supporting destruction is clarified that the load process of supporting structure can not be coordinate with the process of the surrounding rock deformation. Follow the basic principles that Supporting should be coordinate with the surrounding rock,a new structure of lining is proposed.
