摘要
北京地铁8号线三期工程穿越既有10号线运行区间,为确保运行线路安全平稳营运,必须将结构变形控制在可控范围内。锁扣管幕施工能够最大程度的控制结构沉降,确保运行线路平稳。利用管幕施工的特点,结合北京地铁8号线三期工程实例,深入开展对锁扣长管幕技术分析研究,依靠先进的监测设备,总结出经济、合理、可行的针对严格控制沉降的管幕施工工艺,总结出关键技术指标,为其他类似工程提供宝贵经验及技术参数。
The third phase project of Beijing Metro Line 8 passes through the operation section of the existing Line 10.In order to ensure the safe and stable operation of the operation line,the structural deformation must be controlled within the controllable range.Lock pipe curtain construction can control the structure settlement to the greatest extent and ensure the smooth operation of the line.Based on the characteristics of pipe curtain construction,combined with the third phase project of Beijing Metro Line 8,the paper carries out in-depth analysis and Research on the lock lock long pipe curtain technology.Relying on the advanced monitoring equipment,it summarizes the economic,reasonable and feasible pipe curtain construction technology for strict settlement control and summarizes the key technical indicators,so as to provide valuable experience and technical parameters for other similar projects.
