目前,国内城市地铁隧道施工越来越广泛地使用盾构机,尤其是上海、广州和北京等城市地铁隧道采用盾构法施工非常普遍,其他城市如深圳、南京、天津、成都、杭州和西安等城市也在地铁隧道施工中采用盾构法施工。由于广泛使用盾构法施工,国内盾构施工水平也在不断提高,盾构施工工法正在日趋成熟。但是,目前国内盾构施工和管理上还普遍存在一些突出的问题,这些问题直接影响隧道的施工安全、工程质量及施工进度,并影响工程项目管理,本期我们探讨盾构法施工中存在的问题及解决方法。
At present, shield tunneling machines are being used more and more widely in domestic urban subway tunnel construction. In particular, shield tunneling is very common in urban subway tunnels in Shanghai, Guangzhou and Beijing. Other cities such as Shenzhen, Nanjing, Tianjin, Chengdu, Hangzhou and Xi’an Other cities are also using the shield construction in subway tunnel construction. Due to the extensive use of shield construction, the domestic shield construction level is also constantly improving, shield construction method is maturing. However, there are still some outstanding problems in the current construction and management of the shield in our country. These problems have a direct impact on the construction safety of the tunnel, the quality of the construction and the progress of the construction, and affect the project management. In this issue, we discuss the problems existing in the construction of the shield Problems and solutions.
