摘要
结合某地铁车站下穿地铁环线,隧道埋深浅且地质条件差,经过充分的技术论证,车站采用“柱洞法”下穿既有线,并综合应用了多种复杂的施工技术,解决了很多技术难题,推动了“浅埋暗挖法”在城市地下工程的应用与发展。
In view of the shallow depth and unfavorable geological conditions of one subway station beneath existing subway tunnel, based upon technical demonstration the “pioneer heading-column” method is adopted, combined with the application of various complicated construction techniques many difficulties are resolved, which promote the application and devdopment of shallow tunnding method in urban underground works.
