The Tenth International Symposium on Mitigation of Geo-disasters in Asia Matsue Symposium Place: Shimane Civil Center, Matsue Date: 8 October 2012 The formation and development of landslide at K178 + 530 section of Bei'an-Heihe expressway was mainly affected by armchair shape topography of the slope, hydrologic and climatic conditions, frost-heave cycles, and geotechnical engineering activities for highway construction.
