Abstract: The construction scheme of tunnels passing through landslide area and fault zone of the repair tunnel for Changkou water
tunnel of Zhangjiu River water diversion and supply project in Kunming is introduced in detail, including such contents as description
of tunnel collapse to ground surface, ground settlement pit treatment, collapse body treatment in tunnel, constructuon procedure and
technical measures of pass through landslide area. Construction practice has shown that the tunnel collapse treatment scheme is
reasonable, reliable and effectual.
Key words: tunnel; landslide; construction scheme
1 引言 2 坍方冒顶情况
昆明掌鸠河引水供水工程“输水工程土建Ⅵ厂口隧洞检修支洞主洞上游于 2002 年 11 月 25
标”的主要工程是厂口隧洞,该隧洞全长 11 日掘进到 D79+803 处时,上导掌子面发生小规模坍
m(D74+~D85+),地质条件十分复塌现象,为防止出现坍方冒顶事故,当时决定采取
杂,尤其是厂口隧洞检修支洞主洞 D79+~ 堆码砂袋封闭掌子面注浆加固措施。掌子
