摘要
文章结合梧州至柳州高速公路土建工程№A01-7标段新村隧道"零开挖"进洞工程实例,详细介绍了浅埋偏压隧道采用先施作偏压侧墙后反压回填再暗挖进洞的施工工艺原理及特点,该施工方法的应用,有效减少了对隧道洞口山体及植被的破坏,实现了浅埋偏压隧道"零开挖"进洞,确保了安全进洞及环保进洞,可为类似隧道工程进洞施工提供一定的参考。
Combined with the engineering example of"zero excavation"hole entering of Xincun Tunnel in civil engineering NQA01-7 bid section of Wuzhou-Liuzhou Expressway, this article introduced the construction technology principles and characteristics of shallow-buried unsymmetrical loading tunnel by constructing the unsymmetrical loading side-wall then backpressure back-filling followed with un- derground excavation entering the hole,the application of this method effectively reduced the damage to the hill and the vegetation at tunnel openings, realized the"zero-excavation"entering the hole for shallow-buried unsymmetrical loading tunnel, and can ensure the safe hole-entering and environmen- tal hole-entering,which can provide some reference for the hole-entering construction of similar tunnel projects.
