摘　　要：对盾构隧道工程区间施工距离变化的现状进行梳理,基于4个典型的长距离盾构隧道工程实例,对盾构隧道长距离掘进中出现的刀盘刀具磨损、盾尾密封系统失效、管路磨损、复杂地层盾构开舱、地下对接等问题以及其主要技术原理、技术流程、适用范围及优缺点进行归纳总结,并对我国智能化快速施工技术发展进行了展望。This paper sorted out the current situation of the variation of shield tunnel distance and introduced four typical long-distance shield-tunneling engineering examples. Combined with the typical engineering, five problems in the long-distance excavation, such as the cutter wear, shield tail sealing failure, pipeline wear, opening chamber in complex stratum and underground junction of shield, were systematically analyzed. The principle, technical process, application scope, advantages and disadvantages of main technologies in the long-distance excavation were summarized. The development of intelligent and rapid construction technology has also been prospected. It can provide some references for the formation of a systematic and standardized long-distance shield construction technology in the future.
