广梧高速公路K123处滑坡成因分析及治理

Landslide Cause Analysis and Management of K123 in Guangwu Freeway

滑坡是山区高速公路常见的不良地质现象,根据滑坡的工程地质条件,分析其成因是滑坡治理的关键。文章介绍了广梧高速公路K123处滑坡的工程地质条件和特征,分析了滑坡成因,反算了滑动面的强度值,并在此基础上对采取的工程治理措施进行了稳定性分析,结合滑坡的实际情况,提出了分区采用锚索加钢筋混凝土骨架植草的生态防护形式。滑坡治理已完成两年,目前稳定性良好。

Landslide is a common bad geological phenomenon in mountain area highway, according to the investigation of the engineering geological conditions, the cause analysis of landslide is the key of treatment. This paper introduced the geological situation and character of K123 section in Guangwu Freeway, calculated the strength value of the slip plane. Furthermore, based on the engineering measures to the stability analysis of landslide, combined with the actual situation, the author proposed the partition with anchor cable and reinforced concrete skeleton plant grass ecology protection form. The treatment work has finished for two yeas, at present stability is good.
