摘　　要：为满足隧洞出渣和进料的运输要求,以滇中引水工程香炉山隧洞为例,对隧洞施工过程中竖井的运输能力进行分析,研究竖井采用不同提升方式下的出渣和进料运输能力。分析了吊桶、箕斗和罐笼的提升运输速度和单循环运行时间及隧洞的出渣强度和进料强度,比较了竖井采用3种不同提升方式下的出渣运输能力和进料运输能力,并给出不同提升方式下的提升容器配置,最后根据竖井断面布置得出最优井径。研究结果表明:竖井井径主要由隧洞出渣工况控制,隧洞采用钻爆法施工所需竖井运输能力最小,采用吊桶提升方式所需井径最小。研究成果可为类似竖井工程设计提供参考。To meet the transportation requirements for slagging and material feeding in the tunnel,taking the Xianglushan Tunnel of Central Yunnan Water Diversion Project as an example,the lifting and transportation capacity of the shaft during the tunnel construction process was analyzed,and the slagging and material feeding transportation capacity of the shaft under different lifting methods was studied.The lifting velocity,single-cycle transportation time of the bucket,skip and cage,as well as the slagging strength and feeding strength of the tunnel were analyzed.The slagging capacity and feeding capacity of the shaft under three different lifting methods were compared,and the configurations of lifting containers under different lifting methods were given.Finally,the optimal shaft diameter was obtained according to the shaft section arrangement.The study results show the shaft diameter was mainly controlled by the slagging conditions of the tunnel.The smallest transport capacity of the shaft was required for tunnel construction using the drilling and blasting method,and the smallest diameter of the shaft was required for the bucket lifting method.The research results can provide a reference for similar shaft projects.
