| 摘 要： | 以东滩煤矿14320轨顺联络巷(南段)为工程实例,利用RocData软件将岩石基础力学参数转换成岩体力学参数,再利用Phase2有限元分析软件建立巷道断面及支护设计的数值模型。通过对比分析巷道围岩在支护前后的形变场和塑形场分布规律,理论上验算了巷道支护设计强度,再结合现场实际支护效果,为其它类似巷道的支护设计和后期加固提供了一定的借鉴意义。

| Abstract: | Taking the 14320 track connecting roadway(south section)of Dongtan coal mine as an engineering example,the RocData software is used to convert the rock foundation mechanical parameters into rock mass mechanical parameters,and then the Phase2 finite element analysis software is used to establish a numerical model of the roadway section and support design.Through comparative analysis of the deformation field and plastic field distribution law of the surrounding rock of the roadway before and after the support,theoretically checked the design strength of the roadway support,and combined with the actual support effect on site,it provides support for other similar roadway support design and later reinforcement.A certain reference significance. |
