引汉济渭二期工程某隧洞0+200塌方原因分析

Landslide Cause Analysis of the K0 + 200 Area in a Tunnel of Hanjiang River to the Weihe River Project Ⅱ

引汉济渭二期工程某隧洞出现塌方现象,施工单位对塌方段能否处理和后续隧洞能否继续开挖提出异议,分析塌方现象、塌方段洞室附近地质条件及塌方原因,得出对塌方工程处理是可行的,后续隧洞加强支护是可以成洞的结论。

One tunnel of Hanjiang River to the Weihe River Project Phase Ⅱ occurred landslide, so construction unit questioned whether the collapse section can be treated and follow-up of the tunnel can continue to be dug or not. Based on the consideration of collapse and the geological conditions of the collapse area, this article analyses the causes of land-slides. Therefore, it obtains the conclusion that the treatment of landslide area can be carried out. So, the tunnel can continue to be dug through the method of strengthening the support and protection.
