Abstract: Southwest China has difficult mountainous terrain，and complex geological conditions．During the process of railway，highway，municipal construction and other projects，bedding cut slope is a common geological diseases，and landslide prone handled properly．Based on the agricultural park along the road cut slope control design，bedding cut slope on failure mode and shear strength and length of sliding are discussed．And through many years of governance after the completion of the test project，the design is proved to have good governance results．Similar governance bedding cut slope has some useful referenee value．

Key words: bedding cut slope, sliding zone length, strength, sliding force

摘要： 西南山区地形困难，地质条件复杂，铁路、公路、市政等工程建设中，顺层切坡是常见的地质病害，处理不当易 产生工程滑坡。根据农业园区道路顺层高切坡治理设计，分析了顺层切坡的破坏模式、滑带抗剪强度和长度的确 定，并经过治理工程竣工后多年的检验，效果良好，对类似顺层切坡的治理有一定的借鉴和参考价值
