摘要
含有基岩的边坡在我国广泛分布,然而基岩倾角对边坡稳定性影响的分析尚无较为可靠的研究。为此,采用MIDAS GTS有限元分析软件,根据基岩在边坡中倾角的不同,建立了对应的分析模型,并对不同基岩倾角下边坡的塑性扩展模式进行研究。通过分析发现:随着基岩倾角的不断增加,边坡稳定性不断提高,且增幅变大。最后,结合相关文献,从基岩分布位置对边坡塑性扩展带的影响和坡面滑体体积的角度对有限元结果进行了阐述,以期为含有基岩的边坡稳定性分析提供参考。
Slopes containing bedrock are widely distributed in China, but the analysis of the influence of bedrock inclination on the stability- of slopes has not been reliable research. Based on these, using MIDAS GTS finite element analysis software, according to the different inclination of the bedrock in the slope, the corresponding analysis model was established, and the plastic extension modes of the slope under different bed- rock inclination angles were studied. Through the analysis, it is found that with the constant increase of the bedrock inclination, the stability- of the slope is continuously improved and the increase is greater. Finally, combining with the related literature, the finite element results are elabo- rated from the influence of the bedrock location on the plasticity expansion zone of the slope and the volume of the sliding surface of the slope, in order to provide reference for the analysis of slope stability- with bedrock.
