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。
Aiming at the sensitivity problem of reverse dumping slope deformation, orthogonal test design and path analysis are combined. Based on the numerical simulation results, the slope angle, dip angle, layer thickness, slope height, interlayer friction angle and volume modulus A total of six factors as the main factor. In addition, the effect of interaction between factors on the output effect is further analyzed by taking into account the theoretical advantages of orthogonality and path analysis in the experimental set designed by the orthogonal experiment. The results show that the main influencing factors of the main factors of the rotational deformation of slope are the slope height> slice thickness> slope angle> dip angle> structural surface friction angle, and the bulk modulus is the secondary influence factor of rotational deformation. The interaction factor The most important combination is the slope height - dip angle, and mutual synergy.
