摘 要:以高黎贡山超深竖井服务隧道多断面开挖施工为工程背景,结合SUMO微观交通数值仿真软件模拟结果,对井底车场、井下物流组织以及竖井垂直运输系统开展优化研究。研究表明:井底采用无轨运输替代有轨运输,使竖井出渣能力提高至1 000 m3/d,增幅达25%,井底车场布局、断面尺寸及洞室配置优化后,有效提高运输效率并降低成本;基于井下物流组织数值仿真结果,渣土运输车的平均运行速度为最大设计速度的74%;当掌子面至井底车场距离增至500 m并增设横通道时,虽未出现交通冲突点,但车辆车距过近,存在堵车风险。针对竖井垂直运输系统,实施主、副井改绞换装,并对提升系统进行选型与安全验算,提出了相应的安全控制措施。The multi⁃section excavation of the ultra⁃deep shaft service tunnel in Gaoligong Mountain was used as the en⁃gineering background,and the optimization of the shaft bottom yard,underground logistics organization,and vertical shaft transportation system was conducted based on the results of SUMO microscopic traffic numerical simulation soft⁃ware.The research results showed that rail transport at the shaft bottom was replaced with non⁃rail transport,which in⁃creased the shaft′s mucking capacity to 1000 m3/d,representing a 25%improvement.The layout of the shaft bottom yard,cross⁃sectional dimensions,and chamber configuration were optimized,which significantly enhanced transporta⁃tion efficiency and reduced costs.Numerical simulation results of underground logistics organization showed that the av⁃erage operating speed of muck transport vehicles was 74%of the maximum design speed.When the distance between the face and the shaft bottom yard was increased to 500 m and a cross⁃passage was added,no traffic conflict points were ob⁃served;however,when the vehicle spacing was too close,there was a risk of congestion.The vertical shaft transporta⁃tion system was upgraded by modifying the hoisting systems in both the main and secondary shafts.The hoisting equip⁃ment was selected,and safety verification was performed,with corresponding safety control measures proposed.
