摘要： 以闽西地区龙岩厦蓉高速公路改扩建工程K154段左侧超高土质边坡工程病害为例，开展边坡病害变形特征分析，研究揭示其病害成因。在此基础上，提出采取刷方卸载、锚固支挡强腰、坡脚挡墙固脚以及排水工程相结合的综合工程措施，并结合工程稳定性评估，通过数值仿真方法和现场量测分析验证了所采取工程治理措施的有效性。研究结果对类似超高土质边坡病害治理具有借鉴意义。

Abstract: This paper presents a case history of the evaluation of a landslide at the high soil slope on the lefthand side of Station K154 in the Xiarong Expressway Expansion Project in Longyan of western Fujian. The landslide hazards on the soil slopes were investigated and the mitigation measures were evaluated. These measures included unloading at the crest, anchoring in the middle of the slope, retaining wall reinforcements at the toe of slope and drainage improvements. The sitespecific stability evaluation with numerical analysis was performed and the results were compared with the construction monitoring data. The result of comparison indicate that the mitigation measures were effective.
