摘　　要：应力路径就是指土体受力发生、发展和变化的过程。在采用传统路堤稳定计算方法分析的基础上,基于应力路径的基本概念和太沙基破坏模式确定应力路径分析法中关键点的选取原则,并在饱和深厚软土条件下通过该点的有效应力和超孔隙水压力的转化关系反演得到后处理施工先填方高度的一个简化计算公式。Stress path refers to the process of occurrence,development and change of soil force.Through the analysis of traditional method of embankment stability,the principle of selecting of key points in the stress path analysis method is determined on the basis of the basic concepts of stress-path and sabotage model of Terzaghi,the pre-filling height of post-processing technology is obtained by counterdeduce the relationship between effective stress and pore water pressure of the point of saturated soft soil groundwork,a calculation formula of pre-filling height is given for the convenient application of engineering
