    薄层软基上加筋垫层路堤稳定计算的简布条分法

    APPLICATION OF JANBU LAW TO STABILITY ANALYSIS OF REINFORCED EMBANKMENT OVER THIN SOFT FOUNDATION SOILS

    • 摘要: 针对薄层软土地基的特点,本文在简布条分法基础上研究建立加筋垫层路堤整体稳定性的分析方法。在一定假设条件下,根据加筋垫层的作用原理,通过对筋材受力分析和加筋垫层路堤的整体稳定极限平衡分析,推导出针对薄层软土地基的安全系数表达式和条间切向力H_i的表达式,通过迭代求解建立基于简布条分法的加筋垫层路堤整体稳定安全系数表达式。继而采用Python语言,对本文提出的加筋垫层路堤整体稳定性评价方法实现编程,并结合实际案例进行计算分析,验证所建立稳定性分析方法的可行性。

       

      Abstract: This paper studies the overall stability analysis method of the establishment of the corresponding reinforced embankment on the basis of Janbu Law, in light of the characteristics of thin soft foundation. Under certain assumed conditions, thin layer of soft foundation safety coefficient expression and the tangential force of expression are deduced in accordance with the principle of reinforced cushion action principle and through the stress analysis of reinforced material and the overall stability of the embankment limit equilibrium analysis of reinforced cushion. The overall stability and safety factor of reinforced embankment cushion based on Janbu Law are obtained through iteration. Then, Python language is adopted to program the overall stability evaluation method of reinforced embankment proposed in this paper. Combined with the calculation and analysis of practical cases, the feasibility of the established stability analysis method is verified.
