【摘要】：针对反向倾倒边坡变形的敏感性问题,将正交试验设计和通径分析相结合,基于数值模拟的试验结果,筛选坡角、倾角、层厚、坡高、层间摩擦角和体积模量共六项影响因素作为主因子。此外,由于兼顾正交试验设计的试验组正交性和通径分析的理论优势,进一步分析了因子间交互作用对输出效应的影响。结果表明,坡面转动变形量主因子的敏感性影响总排序为坡高层厚坡角倾角结构面摩擦角,体积模量对于转动变形量为次要影响主因子;交互作用因子中最主要的组合为坡高-倾角,且互为协同作用。
[Abstract]:Based on the results of numerical simulation, six factors including slope angle, dip angle, layer thickness, slope height, friction angle between layers and bulk modulus are selected as the main factors. In addition, the orthogonality and path of the orthogonal test group are taken into account. The results show that the sensitivity of the principal factors to the rotational deformation of the slope surface is in the order of the friction angle of the high-rise inclined structure surface, and the bulk modulus is the secondary factor to the rotational deformation. For slope height - dip angle, and mutual synergy.
