| 摘 要： | 齐岳山隧道F11断层纵向长235 m,断层处主要为高压富水软弱围岩.施工中通过改变原有的注浆施工理念,将原帷幕注浆“柱加固模式”,优化为“桶状加固模式”；通过不断的技术优化,在保证注浆施工质量和开挖施工安全的前提下,将原全断面帷幕注浆192个孔优化为102个,将注浆工期从288天提前为133天.实践证明,围岩加固技术在投资、工期等方面较全断面帷幕注浆法具有比较明显的优势.

| Abstract: | The F11 fault of the Qiyueshan Tunnel is 235 m long vertically,and is mainly located in water-abundant high-pressure soft rock.The original curtain grouting method of column mode was changed to the barrel model. In addition,the original 192 full-face grouting holes were optimized to 102 holes,while the grouting period of construction was shortened to 133 days from 288 days.These practices show that the rock reinforcement technique has obvious advantages over full-face curtain grouting in terms of investment... |
