摘　　要：文中针对某调水工程TBM3-1掘进段,因围岩破碎发生2次卡机事故的处理措施,以及为提高TBM3-2掘进效率,保证按期完工而对敞开式TBM进行的升级改造,保证按期完工而进行了详细论述,使其既具有敞开式TBM模式又具有单护盾TBM模式功能,降低TBM3-2掘进段复杂地质的施工风险。敞开式单护盾多功能双模式TBM在新疆某调水工程中的成功应用,为TBM通过强岩爆、长大破碎带等不良地层提供了强有力的技术保障。In this paper,the treatment measures of two machine jamming accidents occurred in the driving section of TBM3-1 of a water diversion project due to the breaking of surrounding rock and the upgrading and reconstruction of open TBM to improve the driving efficiency of TBM3-2 and ensure the completion on time are discussed in detail.So that it has the function of open TBM mode and single shield TBM mode,which reduces the construction risk of complex geology in TBM3-2 tunneling section.The successful application of open-type single shield multi-functional dual-mode TBM in a water diversion project in Xinjiang provides a strong technical guarantee for TBM to pass through bad strata such as strong rock burst and long fracture zone.
