浅析某隧道斜井工区软弱夹层超前预加固方案

On pre-reinforcement scheme at soft intercalation in working area of inclined shaft in some tunnel

介绍了梁山隧道1号斜井工区软弱夹层超前预加固三个预设计方案,结合工程特点针对三个预加固方案的优缺点进行了分析,指出水平旋喷方案施工速度快、强度高、成本低、抗渗性好,相比其他两种方案优势突出。

The paper introduces the three pre-design schemes for the pre-reinforcement scheme at soft intercalation in working area of No. 1 inclined shaft in Liangshan tunnel, analyzes the advantages and disadvantages for the three pre-reinforcement schemes by combining with the engineering characteristics, and points out that the horizontal jet-grouting scheme has fast speed, high strength, lower costs, sound anti-seepage, so it has outstanding advantage than the others.
