为探究有限埋深抗滑桩加固边坡的稳定性分布规律,基于点安全系数确定边坡的临界滑动面,分析不同屈服准则对确定滑动面位置的影响,研究了桩埋深不同时潜在滑动面的变化趋势及埋深相同时沿边坡纵向滑动面的分布规律。结果表明,考虑带抗拉强度的Mohr-Coulomb破坏准则的点安全系数确定的边坡滑动面最深;随着桩埋深的增加,边坡的稳定性先增加后减小;相同桩长下,沿边坡纵向边坡稳定性先减小后增加。
In order to explore the stability distribution of the slope reinforced by anti-slide piles with limited depth, the critical slip surface of the slope is determined based on the point safety factor. The influence of different yield criterion on the determination of the sliding surface position is analyzed. The trend of the surface and the distribution of longitudinal sliding surface along the slope when the depth is the same. The results show that the slope sliding surface determined by the point safety factor considering the Mohr-Coulomb failure criterion with tensile strength is the deepest. With the increase of the pile depth, the slope stability first increases and then decreases; for the same pile length, The stability of the longitudinal slope along the slope first decreases and then increases.
