Paper Title:
Recovery Execution in Landslide at the Portal of Highway Tunnel
  Abstract

The main feature of NATM is to utilize all available means to develop the maximum self-supporting capacity of the surrounding rock or soil itself, and to undertake investigation and monitoring during construction to provide the stability of the tunnel. If undetected worse ground condition is encountered, the strengthening works will be carried out to ensure safety. In this case study, taking the Wangkeng tunnel portal engineering of the Jiyuan-Shaoyuan Expressway in Henan Province as an example, the calculation and evaluation of landslide stability are performed by limit equilibrium method and FEM. Based on the results of stability analysis, the anti-slide piles and ground drainage are adopted as the harnessing measures of landslide. Comparison of stability analysis before/after landslide harnesses was made by FEM. The results show that these treatments can satisfy the design requirements. It could be a useful reference to the design and construction of tunnels with soil entrance.
