Accurately understanding the instability mechanisms of surrounding rock in deep hard rock roadways is of great engineering significance for the design of roadway support parameters. Taking the kilometer-deep marble roadways at the Jinchuan mine as the research object, a self-defined heterogeneous material program was developed based on the voronoi joint network and Weibull distribution function built in RS2 using the continuous-discontinuous numerical simulation method. A heterogeneous-joint finite element model for the rock and rock mass was established, the deformation parameters and mechanical parameters of marble were calibrated, and the deformation and failure law of deep hard rock was revealed. Meanwhile, considering the joint characteristics of the surrounding rock in the roadway, a heterogeneous-joint finite element model for the roadway was constructed, which reproduced the failure characteristics of deep hard rock roadways. A local support scheme was proposed to address the failure laws of unsupported roadways. The study indicates that the rock and rock mass models constructed based on the heterogeneous-joint finite element method can effectively characterize the deformation and failure laws of deep hard rock. The simulation results of the heterogeneous-joint finite element roadway model are consistent with the the field roadway damage, thereby validating the rationality of this method. Compared with the unsupported condition, the maximum depths of the plastic zones in the left and right ribs of the roadway were reduced by 62.9% and 58.0% respectively after the application of the local support scheme, the numbers of block and joint failures decreased by 83.0% and 74.5% respectively, and the maximum deformation of the roadway was reduced by 33.8%, which verifies the reliability of the local support scheme. The research results provide a reference for the analysis of failure characteristics of surrounding rock in deep hard rock roadway, and expand the idea of deformation control of surrounding rock in deep hard rock roadway.

准确地认识深部硬岩巷道围岩失稳机理，对巷道支护参数的设计具有重要的工程意义。以金川矿千米埋深的大理岩巷道为研究对象，采用连续－非连续数值模拟方法，基于RS2内置的voronoi节理网与Weibull分布函数开发了自定义非均质材料程序，建立了非均质－节理有限元岩石、岩体模型，标定了大理岩变形参数与力学参数，揭示了深部硬岩变形破坏规律。考虑巷道围岩节理特征，构建了非均质－节理有限元巷道模型，复现了深部硬岩巷道破坏特征；针对无支护巷道破坏规律提出了局部支护方案。研究表明：基于非均质－节理有限元法构建的岩石、岩体模型可以表征深部硬岩变形破坏规律；非均质－节理有限元巷道模型模拟结果与现场巷道破坏情况一致，验证了此方法的合理性；相较于无支护情况，应用局部支护方案后巷道左、右帮塑性区最大深度分别减小了62.9%、58.0%，块体、节理破坏数量分别减少了83.0%、74.5%，巷道最大变形量减小了33.8%，证明了局部支护方案的可靠性。研究成果为深部硬岩巷道围岩破坏特征分析提供了参考，拓展了深部硬岩巷道围岩变形控制的思路。
