摘要
隧洞开挖过程中围岩塌方是常发生的事情,塌方后如何迅速妥善处理,保证后续安全施工十分关键。本文详细论述了大伙房水库输水工程10号主洞开挖过程中出现了大断面塌腔情况,对塌腔原因进行了分析,论述了塌腔处理详细措施,为类似工程提供了宝贵经验。
The surrounding rock collapse is often happen in the process of the tunnel excavation,how to quickly and properly handle the collapse to ensure the follow-up safe construction is key.The paper elaborates the large cross section collapse cavity situation in the excavation process of the main tunnel 10# for the Dahuofang reservoir water conveyance project,analyzes the causes of collapse and discusses the detailed treatment measures for the collapse cavity,which could provide the references for similar projects.
