摘要
隧道穿越巨型溶洞过程中的安全处置研究对于我国岩溶区隧道施工具有重要意义。依托于湖北某隧道,利用数值模拟和现场监测等手段对隧道侧穿巨型溶洞施工过程中的安全问题进行研究,从经济性、安全性等角度提出了“回填+注浆”的综合处置方法,数值模拟和现场监测均表明利用本文提出的“回填+注浆”的综合处置方法可有效控制衬砌结构变形,保障结构受力安全,整体处置效果良好。
For tunnelling in China's karst regions,the investigation of safety measures during tunnel crossing enormous caves is highly es-sential.This study examines safety during the construction of a side tunnel through a huge cavern using numerical simulation and field moni-toring based on a tunnel in Hubei.From an economic and safety standpoint,a thorough disposal strategy called"backfill+grouting"is sug-gested.The"backfill+grouting"measure can successfully regulate the deformation of the lining structure and ensure the safety of the struc-ture,according to numerical simulations and field monitoring.
