【摘要】 建立路基土钉支护加固的数值分析计算模型,对边坡土体的变形及土钉的受力进行分析,数值结果表明:随着边坡开挖深度增加面板位移加大,土钉轴力增加。基于此数值分析建议在工程实际中土钉不等长布置会得到更好的支护效果与经济性。更多还原

【Abstract】 In the paper,establishing numerical analysis model of reinforced subgrade soil nailing and the deformation of the slope soil and the force of the soil nails is analysed systematically.The numerical results show that with increasing the depth of slope excavation and augmenting the displacement of panel,the force of soil nail axial will be increased.Based on the numerical analysis model,a recommendation that using unequal length soil nailing in the actual will get a better supporting effect and benefits.更多还原
