摘　　要：云南省某高速公路通车1年后,堆积体边坡出现了坡面平台开裂、框格梁剪断、锚头崩坏、抗滑桩桩周土体下错等病害。文章通过谷歌地图回放功能分析堆积体的形成过程,并通过补勘、变形监测、稳定性计算等技术手段对病害原因进行了分析。最终采用增设排水沟、截水沟,连通各级平台排水沟等处治方法,取得良好效果。文章给出堆积体边坡加固方法的选择建议,以期为类似工程提供参考。One year after a highway in Yunnan Province was opened to traffic,problems such as cracking of the slope platform,shearing of frame beams,collapse of anchor heads,and subsidence of the soil around the anti-slide piles appeared on the accumulation slope.This article analyzes the formation process of the accumulation body by means of the replay function of Google Map,and conducts the analysis on the cause of the disease by virtue of supplementary survey,deformation monitoring,stability calculation and other technical means.Finally,the treatment methods such as adding drainage ditches and intercepting ditches,connecting drainage ditches together on all levels of the platform,etc.,have been adopted and achieved good results.This paper gives some suggestions on the selecting the reinforcement methods for the accumulation body's slope,in order to provide reference for similar projects.
