摘要
五里牌滑坡位于新晃县城以西约3km的五里牌村,系上海至瑞丽国道主干线怀新高速公路滑坡。该滑坡形态复杂,经勘察和分析认为:滑坡为牵引式和推动式共同作用形成;根据其形态,可分为1#和2#两个滑坡体,其中1#滑坡体又可分为Ⅰ、Ⅱ两个分区;Ⅰ区滑坡体在往北东方向为主的滑移过程中,遇右侧硅化含砾砂岩阻挡,形成反力,往Ⅱ区产生北西方向的扭转变形。
Wulipai landslide is situated in Wulipai, 3 km western Xinhuang county and formed by construction of Huaihua-Xinhuang express way. Based on the investigation and analysis, the configuration of the landslide is complicated, which is the result from the pulling and pushing force. The landslide is divided to 2 landslide bodies and for the first body may be divided to 2 parts, the reason is that the first body met the resistance from silicate sandstone and the torsional movement towards northern-west happened, when the first body was sliding mainly to northern-east.
