粤北山区煤系地层高边坡稳定性分析及治理设计

以粤北山区某高速公路K227+210～+385右侧煤系地层路堑高边坡滑坡为例，阐述了滑坡区工程地质和水文地质条件，采用折线型不平衡传递系数法对滑坡稳定性进行了计算和评价。根据滑坡的分布范围、变形特征、诱发因素、稳定现状与趋势等，并考虑施工风险、工期及质量控制等因素，提出滑坡综合处治方案。

Stability Analysis and Control Design of High Slope in Coal Measure Strata in Mountainous Area of North Guangdong

The landslide along the high cutting slope in coal measure strata on the right of the K227+210~+385 section of a highway in mountainous area of north Guangdong was taken as the example to describe the engineering geological and hydrogeological conditions thereof, and make the calculation and evaluation on the landslide stability by broken-line imbalanced transfer coefficient method. According to the landslide distribution range, the deformation characteristics, the inducing factors, and the status quo and trend of stability, with the construction risks and period and the quality control taken into consideration, the comprehensive control scheme for the landslide was proposed.
