摘要
为选择合理的山区边坡滑塌治理方案,对常用的加固方法如抗滑桩、预应力锚索框架梁、抗滑桩和锚索组合等抗滑结构进行分析,结合贵州省六威高速一处施工实例,提出3种加固方案:削方减载、削方减载与抗滑桩、削方减载与设置路堑挡土墙,并从施工工期和经济性等方面对3种方案进行比较,最终选择科学合理的方案,为同类施工提供借鉴。
In order to select a reasonable treatment scheme for slope sliding in mountainous area, the commonly used reinforcement methods such as anti-sliding piles, prestressed anchor cable frame beams and the combination of anti-sliding piles and anchor cables were analyzed. Based on a construction example on Liuwei Expressway in Guizhou Province, three reinforcement schemes were proposed, including reducing load by cutting earth, reducing load by cutting earth while using anti-sliding piles, and reducing load by cutting earth while setting the retaining wall. The schemes were compared from the aspect of construction period and economy, and finally a scientific and reasonable one was selected, providing reference for similar construction.
