粘质土路基稳定性分析方法的研究及应用

Research and Application of Clay Roadbed Stability Analysis

建立了粘质土路基稳定性分析中求算相关角值的数值公式,并在此基础上重新编制了相关角值表,可替代流行至今但精度较差的现行角值表.对于软粘土路基的稳定性分析,通过力学分析建立了某一边坡高度的各种可能破坏面的最小稳定系数Kmin的解析公式.在与现行规范法对比的基础上,阐明了该法的实用价值.

This paper sets up the numerical equation to calculate relevant angle figures in the stability analysis of clay roadbed and works out the relevant angle figure chart again to replace the current one that is worse in its accuracy. Through mechanics analysis, the stability analysis of soft clay roadbed sets up an analytic equation of the figure 揔min?of the various possible destructed surfaces of a certain sloping side height. Compared with the current standard method, this paper explains the practical value of the method expounded in it.
