摘　　要：简要总结了复合土钉支护技术的主要优点、作用机理、组合形式及使用条件,研究分析了厚填土边坡的复杂破坏模式,通过工程实例,介绍了土钉、加筋土与轻型挡墙相结合的复合锚固技术在某水毁厚填土边坡工程的应用,简述了该加固工程的背景、施工技术方案和施工方法,并依据监测结果提出了具体建议。实践表明:边坡破坏模式的正确选取是对该类工程进行稳定性分析和方案设计的基本依据,做好全方位的防、排水处理措施是该类工程成功的关键。In this paper, the working mechanism, the main characteristic, the structural style and the working conditions of CSNT were briefly summed up. Failure modes of the slope thick filled soil were studied. With an engineering project as the backgroud, the application of nailing in combinaiton with with reinforced soil and light retained wall in a thick filled soil slope were introduced. This practical project showed that the correct selection of the slope failure mode is the basis for stability analysis and scheme designfor. The application of the all-wave water-resistant and the drainage system are the key components for similar engineering projects.
