自封闭全接触碹体支护的力学原理与参数设计

The Mechanical Principle and Parameter Design of Self-closed and Full-connected Arch Walling Support

在分析自封闭全接触碹体支护巷硐周围不同区域应力分布规律的基础上 ,得出了围岩极限平衡区半径同巷硐所处的原岩应力 ,围岩本身的物理力学性质及碹体支护参数间的相互关系 ,提出了设计碹体厚度的计算公式 ,为实际进行支护设计提供了理论依据。

Based on the analysis of the stress distribution law in different districts around the self closed and full connected arch walling support roadway,the relationship among the limit equilibrium radius and the in situ rock stress,the physico mechanical properties and support parameters is obtained.The calculation formula of arch walling width design is put forward so as to provide a theoretical basis for the practical design of support.
