摘　　要：选取漳州招银高速公路工程典型路堑边坡进行稳定性分析及其加固措施研究,考虑天然工况和暴雨工况。通过稳定性分析,自然条件下的安全系数在两种工况下的安全系数均较低;设置锚索加固措施后,两种工况下的安全系数稍有提高;若采用锚索抗滑桩综合加固措施,安全系数提高较大。由于该边坡地质条件的特殊性,建议进行动态设计。Zhao-Yin Expressway in Zhangzhou passes through the Zhongshan Formation, which is typical for its complicated folding and rupture in technic structures with different degrees of weathering. The rolling terrain with typical eroding is also typical in physiography. This paper presents a case study of the analysis and mitigation of the typical highway slopes in this project. In addition to the natural conditions, the effect of the heavy rain on the slope stability is also evaluated. Throughout the stability analyses, the factors of safety are also not acceptable under normal and heavy rainfall conditions. When the slopes are reinforced with ground anchors, the stability is slightly improved. When the ground anchors as well as the anti-sliding shafts are used, the factors of safety can he significantly improved. Due to the special conditions of these slopes, it is suggested that the stability design should be modified during the construction.
