摘要
北京地铁七号线富水砂层盾构区间联络通道利用冻结法加固土体顺利完成施工,本文详细介绍了冻结法设计、施工以及信息化监测技术,为北京地铁联络通道水平冻结施工提供了参考依据。本工程的成功经验可供其他相似工程参考。
The freezing ground method was used to successfully complete the construction of the connecting passage of the Beijing Metro Line 7 shield tunnel in a water-rich sandy stratum.The design,construction,and information monitoring technology of the freezing method in this project are introduced in detail in this paper.This study provides a reference for the horizontal freezing construction of the Beijing subway connecting passage.The successful experience of this project can also be used as a reference for other similar projects.
