基于由注浆量统计结果得出的支护－围岩接触关系，通过数值计算全面、系统地分析了支护－围岩接触关系对支护－围岩承载体系的影响规律和碹体支护失稳破坏的内在机制，分析了支护体上载荷分布与其破坏形式的关系，为改进现有碹体支护工艺提供了一定的理论基础．
Based on the contact relationship between the support and the surrounding rock, which is calculated by the grouting amount, the influence law of the contact between the support and the surrounding rock on the bearing system of the support-surrounding rock is comprehensively and systematically analyzed by numerical calculation, The internal mechanism of instability and failure is analyzed. The relationship between the load distribution and its failure form is analyzed, which provides a theoretical basis for improving the existing bracing technology.
