复合式 TBM 脱困施工技术复合式 TBM 脱困施工技术 摘要:盾构或复合式 TBM 在城市地铁施工中占主导地位,其有很多优点如施工速度快、干扰较小、自动化程度高、开挖安全和衬砌同步等
但假如出现地层变形复合式 TBM 盾壳被卡死,不能进行推动,复合式 TBM 就失去了快速推动的优势
本文重点叙述针对本工程复合式 TBM 盾壳抱死处理措施,从刀盘土仓内爆破施工、盾壳上部爆破施工、地表房屋监测、支护、脱困推动等方面进行阐述,为以后的城市地铁施工盾壳被卡提供较有用的参考事例

But if the stratum deformation of composite TBM shield was stuck there, not promote, composite TBM lost the advantage of rapid advance
This paper focuses on the engineering of composite TBM shield locking measures, is described from the cutter head chamber blasting, the blasting construction, shield shel
