【摘要】：針對(duì)反向傾倒邊坡變形的敏感性問(wèn)題,將正交試驗(yàn)設(shè)計(jì)和通徑分析相結(jié)合,基于數(shù)值模擬的試驗(yàn)結(jié)果,篩選坡角、傾角、層厚、坡高、層間摩擦角和體積模量共六項(xiàng)影響因素作為主因子。此外,由于兼顧正交試驗(yàn)設(shè)計(jì)的試驗(yàn)組正交性和通徑分析的理論優(yōu)勢(shì),進(jìn)一步分析了因子間交互作用對(duì)輸出效應(yīng)的影響。結(jié)果表明,坡面轉(zhuǎn)動(dòng)變形量主因子的敏感性影響總排序?yàn)槠赂邔雍衿陆莾A角結(jié)構(gòu)面摩擦角,體積模量對(duì)于轉(zhuǎn)動(dòng)變形量為次要影響主因子;交互作用因子中最主要的組合為坡高-傾角,且互為協(xié)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.
