北京地铁6号线玉带河大街站一郝家府站区间联络通道采用了冻结法施工,本文介绍了该工程冻结法施工参数设计以及施工中的技术措施、难点和对策,为类似工程提供经验积累。施工监测数据显示,本工程采用冻结法施工有效控制了地表沉降,与传统浅埋暗挖方法相比,在施工技术难度、造价、工期等方面均具有一定的优势。
This paper introduces the construction parameters design of freezing method and the technical measures, difficulties and countermeasures in construction, providing experience accumulation for similar projects. This paper introduces the freezing method construction in the intercourse passage of Haojiafu Station in Jade River Station of Beijing Metro Line 6, . Construction monitoring data show that the construction of the project by freezing control effectively control the surface subsidence. Compared with the traditional shallow burying method, it has certain advantages in terms of construction technology difficulty, cost and construction period.
