【摘要】 目前,隧道掘进机的机械化及自动化水平得到了很大提高,隧道掘进机可以开挖不同的地质条件下各种形状的隧道。隧道掘进机的类型也越来越多,根据隧道工程场地所处的水文地质与工程地质条件,工程的使用特性及环境的限制,不同类型的隧道掘进机的工作机理需要进一步的理解并依此进行分类,以便选择合适的隧道掘进机。本文介绍了各种类型的全断面隧道掘进机的运行机理,并根据最终开挖隧道断面,掌子面的支护类型及岩土体的破碎机理对全断面隧道掘进机进行分类。本文也总结了各类型的隧道掘进机的应用范围。使用者可根据地质条件及特殊需要对隧道掘进机进行初步的选型。更多还原

【Abstract】 At present,the level of mechanization and automation of tunnel boring machines(TBM) has been improved significantly,and TBMs can be designed to excavate tunnels with different shapes under different geological conditions.The types of TBMs are becoming more versatile.In order to facilitate selection of TBMs in a project based on engineering geology and hydrogeology conditions,project characteristics and environmental constraints,it is necessary to understand the operation mechanisms of different TBMs and classify them accordingly.In this paper,the authors describe the operation mechanisms of each type of full-face TBM,and classify full-face TBMs by their final excavated tunnel section,immediate support mechanism and cutting mechanism.Based on applicability of each type of TBM,users can select appropriate TBMs to meet their needs and geological conditions.更多还原
