摘要
文章通过调查和研究十天高速某碎石土滑坡的工程地质条件和诱发因素,对碎石土滑坡的成因和稳定性进行定性、定量综合评价,提出应用分离式预应力锚索抗滑桩进行治理设计,并采用有限差分弹性地基梁法进行治理设计计算分析。分析结果表明:坡脚人工活动及强降雨是碎石土滑坡产生的主要诱发因素;分离式预应力锚索抗滑桩应用于碎石土滑坡治理是合理和有效的。
Through investigation and research on engineedng geological conditions and predisposing factors of a gravel soil landslide in ShiUan Expressway, this article conducted the comprehensive qualitative and quantitative evaluation on the causes and stability of gravel soil landslide, proposed to use the separate prestressed anchorage anti-slide pile for the treatment design, and used the finite difference elastic foundation beam method for the treatment design calculation and analysis.The analysis results showed that,the human activity and heavy rainfall at the toe of slopes are the main predisposing factors to cause the gravel soil landslide;and the application of separate prestressed anchorage antislide pile in gravel soil landslide is reasonable and effective.
