摘要
某超大深基坑工程存在多层混凝土支撑结构,且邻近地铁盾构隧道,通过对支撑拆除工艺的优化完善,顺利完成了复杂工况下的多层混凝土支撑结构拆除工作,并确保了超深基坑结构稳定以及地铁盾构隧道安全,为同类工程提供借鉴经验。
A super deep foundation pit project has a multi-layer concrete support structure and is adjacent to the metro shield tunnel.Through the optimization and improvement of the support removal process,the removal of the multi-layer concrete support structure under complex conditions has been successfully completed,and the stability of the super deep foundation pit structure and the safety of the metro shield tunnel have been ensured,provid which reference for similar projects.
