摘要
盾构下穿既有线盾构隧道施工中,盾构机施工控制的好坏,直接关系到既有地铁线路是否能安全正常的运行,北京市南水北调配套工程东干渠工程6#盾构区间在 K11+799处下穿地铁 M15线,通过盾构下穿 M15线风险源时采取控制措施,使 M15线变形控制在合理范围内,为同类项目施工提供技术支持和借鉴。
The construction control of the shield directly impacts the safe operation of the existing subway line.In the con-struction of No.6 shield section of east main canal of south-to-north water diversion auxiliary project in Beijing,the control measures are taken when the shield underneath through the risk source of the Metro M15 at K11 +799 to control the deform-ation of M15 within a reasonable range,which can provide the technical support and references for the similar project con-struction.
