摘要
通过建立加固后边坡的数值计算模型,研究运煤道路典型荷载作用方式—非对称行车荷载作用下斜坡路基和微型桩的受力与变形特征,分析不同荷载幅值对其影响规律。
Numerical model of reinforced slope under asymmetric traffic load effect, which is the typical load effect mode of coal carrying roads, is established to study the stress and deformation response of slope subgrade and micropile. The influence laws under different load mag - nitudes is analyzed.
