摘　　要：陕西省是软弱变质岩分布广泛的省份之一。近年来,随着工程建设数量的增多和规模的加大,软弱变质岩斜坡灾害频繁发生,造成的损失也逐年增加。本文通过对陕南316国道早阳-蜀河段的实地调查,归纳了该路段软弱变质岩边坡的变形破坏特征,总结出顺层滑动、弯曲-倾倒、楔形体滑动、溃曲破坏以及滑移-拉裂5种典型的病害模式,并对每种变形破坏模式进行了具体的实例分析,从而为边坡成灾预警和选择经济有效的治理对策奠定基础。Shaanxi is one of the provinces where soft metamorphic rock has distributed widely. In recent y.ears, with engineering construction increasing or enlarging, slope hazards have been frequently happening, and the loss has also been increasing year by year. According to the geological survey on No. 316 national road from Zaoyang to Shuhe in the southern Shaanxi province, five deformation and failure patterns of the slope in soft metamorphic rock are concluded and analyzed in detail, for effective forecast and economical treatment of slope hazard.
