高陡岩质临坡地基承载力试验研究与数值模拟
Experimental research and numerical simulation of bearing capacity of high-steep rock foundations near slopes
摘要
Abstract
This study conducted bearing capacity test of high-steep rock slope foundation under different slope angles and slope distances to investigate the bearing capacity of high-steep rock slope founda-tion.We carried out numerical simulation to analyze the influencing factors of the bearing capacity of the high-steep rock slope foundation,combined with the deep waste pit project.The results show that:(1)The capacity coefficient η gradually decreases with the increase of the slope angle β,and increases nonlinearly with the increase of slope distance B.When the slope distance B exceeds a certain value,the bearing capacity coefficient η no longer increases and approximates 1.0.(2)Compared with slope angle β,geological strength index GSI exerts significant influence on the bearing capacity coefficient,and both of them increase nonlinear synchronously.(3)Anchor cable could improve the bearing capaci-ty coefficient η.When four anchor cables are set,the bearing capacity coefficient η demonstrates more significant improvement.Yet,further increase in the number of anchor cables has little effect on the bearing capacity coefficient η.关键词
