摘要
高水压盾构的到达是隧道修建过程中最关键且最危险的环节,在高水压作用下仅依靠传统的单一的加固技术不能很好的保证该段施工的安全性。为解决这一问题,以南京地铁十号线越江段为例,主要介绍其盾构到达过程中采用的冻结法+水中到达法的施工技术要点及注意事项,为其他高水压盾构接收施工提供技术参考。
The achievement of the shield with high water pressure is the most critical and most dangerous link in tunnel construction process.With the high water pressure,the traditional single reinforcement technique can not guarantee the safety of the segment construction well.In order to solve this problem,this paper takes river-crossing section of Nanjing subway line 10 as the example to mainly introduce the construction technology key points and matters needing attention of freezing method ＋ water achievement method in shield achievement process to provide technology references for other shield receiving construction with high water pressure.
