摘要
明暗挖结构洞口接口处的施工工程较为复杂,因此施工质量难以保证。结合哈尔滨市地铁3号线二期工程实例,对传统明暗挖结构洞门接口处施工方法中存在的主要问题进行深入分析。为了改善明暗挖结构洞门接口处施工质量,提出了一种套接式施工方法,通过扩大洞门结构预留尺寸和改变施工缝留设位置,有效解决传统施工方法中存在的问题,并为类似工程的施工提供借鉴和指导。
The construction engineering at the interface between open-cutting and underground evacuating structures is quite complex,leading to poorly controlled quality of construction.Taking the construction practice in phaseⅡproject of metro line 3 at Harbin as the example,we analyzed the main problems existing in the construction on the interface between open-cutting and underground evacuating structures.To improve its construction quality,we proposed a nesting-type construction method.This method can address the problems in the conventional construction practice by extending the reserved cave size and changing the reserved location of construction joints.The proposed method can provide valuable evidence and guide for similar engineering.
