| 摘 要： | 煤系地层易发生人工滑坡，其具有地形缓、滑动面长、下滑力大的特殊性，然而，这种人工滑坡一般都难以处治。针对贵州省晴兴高速公路地久互通滑坡，分析其地质岩性与滑坡机理，进行下滑力计算，在分析计算的基础上提出采用双排桩支挡的方案，取得了良好的处治效果。

Application Research of Double-row Anti-slide Pile for Landslide Treatmentin Coal Measure Strata Highway |
| |
| Abstract: | Human activity induced landslide is easy to occur in coal measure strata, which have the special features of slow terrain, long sliding surface, large sliding force and hard to be treated. Taking Dijiu interconnection landslide of Qinglong-Xingyi highway in Guizhou Province as an example, its geological lithology and landslide mechanism are analyzed and its slide force is calculated in this paper. Based on such analysis and calculation, a scheme of double-row anti-slide pile retaining is proposed, which has achieved good treatment effect. |
