摘要
盾构法是一种使用机械暗挖隧道的施工方法,主要用于断面和功能较单一的区间隧道的施工。此法是在盾构机钢壳体的保护下,依靠其前部的刀盘或挖掘机开挖土层,并在盾构壳体内完成出渣,管片拼装,推进等作业。盾构法施工技术日趋成熟,已逐步成为城市地铁区间隧道的主要施工方法。在上海、广州、北京的地铁工程中大规模、成功地使用了盾构技术。
Shield method is a kind of construction method using mechanical underground tunnel construction, which is mainly used for cross section and single-function interval tunnel construction. Under the protection of the steel shell of shield machine, the front knife dish or excavators are used for digging soil and the work of slag-out, segment assembling and boosting are completed in shield shell. Shield method construction technology is becoming mature, and has gradually become the main construction method of urban subway tunnel In Shanghai, Guangzhou and Beijing subway engineering, this technology has been successfully used in large scale.
