以北京地铁暗挖隧道施工为工程背景,结合当地地质条件,决定采取袖阀管深孔注浆和前进式注浆工艺相结合的施工方案对隧道周围土体进行加固,经数值分析可知加固效果较为显著,从而确保了隧道施工质量。
以北京地鐵暗挖隧道施工為工程揹景,結閤噹地地質條件,決定採取袖閥管深孔註漿和前進式註漿工藝相結閤的施工方案對隧道週圍土體進行加固,經數值分析可知加固效果較為顯著,從而確保瞭隧道施工質量。

Based on the subsurface tunnel construction of Beijing Metro as the engineering background,the study adopts the construction scheme combining the deep-hole grouting with sheathed pipe and the marching grouting craft to undertake the consolidation on the tunnel surrounding earthwork by combining with the current geological conditions,and proves by the numeric analysis that the consolidation effect is obvious,so the method ensures the tunnel construction quality.
