厄瓜多尔CCS项目双护盾TBM通过断层破碎带施工技术研究与实施

Research and implementation of construction technology of double-shield TBM penetrating fault fracture zone in Ecuador CCS Project

本文结合厄瓜多尔CCS项目水电站输水隧洞工程,选取"旁洞+上导洞揭顶开挖"施工方案,使双护盾TBM安全高效通过50米破碎带,形成双护盾TBM快速施工方法,可供同类工程参考。

Based on the water conveyance tunnel project of CCS hydropower station in Ecuador,this paper selects the construction scheme of ＂ side tunnel ＋ top-opening excavation of upper guide tunnel＂ so that the double shield TBM can safely and efficiently pass through the 50-meter crushing zone,forming a quick construction method of the double shield TBM,which can be used as a reference for similar projects.
