摘　　要：复合型土钉支护是近年来针对软土基坑发展起来的一种围护结构 ,已得到广泛应用。根据软土变形的特性 ,采用能反映软土微观变形的结构性模型进行计算分析 ,通过工程实例验证了这一方法的可靠性。A kind of new composite soil nailed retaining wall,composed of soil nail and soil-mixed cement,has been developed and widely used of recent years. On the basis of characteristic of soft soil distortion,calculation and analysis are made by use of a structural model,which can reflect micro distortion of soft soil. The reliability of this method is verified by engineering example.
