英文摘要The evolution of large- scale landslides should be studied because, over long periods of time, primary remediation measures may suffer reduced efficiency or have to be adjusted many times. The 102 Landslide in southeast Tibet, which originally formed in 1991 with a volume of 5.1 million m(3) and still exhibits post- failure activity, provides a distinctive case study. The landslide evolved from earthquake destruction and unloading, rainfall- triggered sliding, and debris flow to sands sliding slopes. The NE ringed scarp receded by 38.96 m during a five- year period (2003-2008). The total recession was 160 m with a total area of 2500 m (2) during a 17-year period (1991-2008). Although several types of remediation measures were applied and were temporarily effective, the normal function of the Sichuan-Tibet Highway was affected by landslide reactivation from time to time. Actual effects of the engineering measures such as retaining walls, prestressed anchor cables, and drainage ditches confirm that hasty governance of this type of large-scale landslide is generally unfeasible over long time periods. Finally, an approach involving a tunnel running backward from the front face has been adopted as a permanent solution to large-scale moraine slope failures: This engineering practice has been in progress since April 2012. This paper describes the evolution of the 102 Landslide, the engineering interventions to mitigate the effects of the landslide on the Sichuan-Tibet Highway, and the choice of tunneling as a final mitigation measure. The present study concludes that approaches that allow escape from developing geohazards should always be the initial choice.
