摘要
针对在土坡稳定性分析中最危险滑面的位置受众多因素的影响,采用临界滑动场理论分析了粘聚力、内摩擦角、土体重度、边坡高度及水平地震系数对不同坡比时均质土坡最危险滑面位置的影响。结果表明,滑面位置随粘聚力增大、内摩擦角减小而逐渐变深,坡高愈大滑面位置浅,重度影响轻微,随水平地震系数的增加坡顶处深度增大、在坡脚处深度减小。
In the slope stability analysis,the position of critical slip surface was determined by many factors.The influence of cohesion,internal friction angle,unit weight,slope height and horizontal seismic coefficient on the position of critical slip surface in homogeneous soil slopes with different slope ratios was discussed using the theory of critical slip field.The results show that,with other parameters invariant,the position of slip surface is deeper with the increase of cohesion and the decrease of internal...
