头沟1号隧道汉中端山体滑坡治理研究

Research on landslide treatment of hills at Hanzhong part of No.1 tunnel of Tougou

对十天高速汉中—略阳段头沟1号隧道左线汉中端施工过程中山体滑坡引起隧道塌陷和桥梁墩柱发生偏位进行了分析,对该处山体滑坡进行治理研究,并结合工程实际,提出相应的施工方案,为山区滑坡地段的公路施工建设提供一定的参考。

The study analyzes the tunnel collapses and bias at bridge piers caused by landslides in the construction process of Hanzhong part at left line of Tougou No.1 tunnel between Hanzhong and Lueyang section along Shiyan-Tianshui Expressway,undertakes the treatment research on the landslides,and points out respective construction schemes by combining with the engineering practice,so it provides some reference for the road construction at mountainous landslide sections.
