摘　　要：本文通过以正交设计原理安排的27个土工格栅加筋土陡边坡模型试验,揭示了众多影响因素共同作用下加筋土陡边坡破裂面位置的变化规律,分析并获得了影响加筋土陡边坡破裂面位置的主要影响因素,并将它们对破裂面位置的影响程度的次序进行了排列,同时发现加筋土陡边坡破裂面形态并非工程界常用的“直线”或“光滑曲线”,而是“锯齿型”的折线,为此对其成因机理作了探讨.<ABSTRACT> Twenty-seven geogrid-reinforced steep slope model tests designed through orthogonal principle have been performed to search for the variable law of failure surface location and its pattern, which is affected by multi-factors. The main factors contributing to the failure surface location have been ob-tained and also have been put in order according to their contributions re-spectively. Meanwhile ,the pattern of failure surface has been found out to be neither 'straight line' ,nor 'smooth-cure' ,but 'saw-tooth broken line'. The cause of its mechanism is also investigated.
