长牛铁路K14滑坡病害原因分析及综合治理

以长牛铁路K14滑坡为例，在现场调查、地质勘察及研究已有资料的基础上，对滑坡产生的原因进行了系统分析。由于边坡下伏基岩向坡外倾斜、坡脚深挖后未设置有效的支挡措施、边坡坡面无防护措施、未采取有效措施引排边坡岩土体内地下水、连续降雨等原因引起斜坡滑动。采用上部刷方减载、坡脚设抗滑桩及重力式挡土墙的综合治理方案，治理完毕一年多，坡体稳定，达到预期效果。

Genesis Analysis and Comprehensive Treatment on Landslide Disease at K14 of Changniu Railway

Taking landslide at K14 of Changniu Railway as the example and depending on field investigation, geological prospecting and study of current materials, the genesis of landslide is analyzed systematically. The slope sliding is caused due to the bedrock underlying the slope inclining outward, no effective support structures set after excavation of slope toe, no prevention measures on the slope surface, no effective initiatives to drain groundwater inside the rock and soil mass, and continuous rainfall. The comprehensive treatment of cutting work to reduce load at the upper slope and setting anti-sliding pile and gravity retaining wall at the toe of slope was adopted more than one year before. Till now the landslide body is stable reaching the prospective effect.
