摘要
依托济南黄河隧道北岸工作井基坑工程,对基坑开挖施工过程进行研究,依据工程实际提出基坑开挖和支护遵循"开槽支撑、先撑后挖、分层开挖、严禁超挖"的原则,有效降低基坑开挖过程产生的风险,保证了基坑施工的安全性.
Abstract
Relying on the construction of the work well foundation on the north bank of Ji'nan Yellow River Tunnel,this study investigates the excavation process of the foundation pit.Based on actual engineering conditions,it proposes excavation and support principles for the foundation pit,including"slotting support,supporting before digging,layered excavation,and strict prohibition of over-excavation".These measures can effectively reduce risks during the excavation process and ensure the safety of pit construction.
