摘 要: | 十(堰)天(水)高速公路K412滑坡为一堆积层老滑坡,线路在滑坡中前通过,随着开挖边坡深度的增加,老滑坡局部复活,且逐步加大,最终可能整体复活。因此,要了解滑坡的空间形态,必须查清滑坡的坡体结构及地下水等其他影响因素,同时结合滑坡的变形特征及钻探、物探、深孔位移监测等勘察手段对其稳定性进行了综合分析,确定老滑坡及复活滑坡目前的安全系数,并对新老滑坡的治理工程设计提出了合理建议。

Abstract: | The landslide at K412 section of Shiyan-Tianshui Highway is an oldaged eolluvial landslide and the road passes right before it. As the excavation height was increased, the oldaged landslide underwent a revival locally to the extent increased gradually, and it may reactivate as a whole finally. Therefore, to known the spatial shape, the body structure, groundwater and other factors affecting the landslide must be checked; at the same time, with the deformation characteristics and some prospecting methods, such as probe drilling, geophysical exploration, deep-hole displacement monitoring, the landslide stability is analyzed comprehensively. As a result, the current safety margins of aged and reactivated landslide are established and rational advices on the treatment design thereof are proposed. |
