| 摘 要： | 采用有限元方法对深埋双轨巷道在无支护和有支护条件下围岩与支护结构的受力及变形特征进行分析,给出两种支护条件下围岩的应力分布特征、巷道周边特征点的变形(位移)大小及破坏区的范围,对支护前后巷道周边特征点处的应力、位移和屈服度进行对比分析,计算了混凝土支护结构所受内力和弯矩的大小,并给出其分布特征图。通过研究得出围岩能够自行稳定、支护结构设计参数合理和原设计方案可行的结论。

| Abstract: | This paper used FEM to analyze the stress,deformation and damageof the surrounding rockand the supporting structureof the double-track roadwayat a mine under no-supported and supported conditions.The characteristics of stress distribution,the size of the deformationand the yield degreeof the surrounding rockunder no-supported and supported conditionswere analyzed and compared.The magnitudeand the distribution maps of the internal force and momentof the concrete supporting structurewere computed and given.Th... |
