摘要
基于圆形巷道在弹性和弹塑性状态下围岩应力分布的规律,详细分析了在不同原岩应力、不同围岩强度条件下围岩承载圈的分布特征及其影响因素,并对承载圈作了进一步划分。最后论述了承载圈的实际工程意义。
Based on the stress distribution around a circular roadway under elastic and elastoplastic conditions, the distribution features and affecting factors of the load-bearing ring in the surrounding rocks with different strengths under various initial stresses are analyzed in detail, and the load-bearing ring is further determined. Finally, the engineering significance of the load-bearing ring is discussed.
