摘　　要：为了确定路基顺层边坡抗滑桩支护方案的合理性,结合实际工程,采用有限元软件分析并确定了施工参数。在此基础上,进一步计算并对比了边坡最大水平位移和安全系数,确定了4~#桩位为最佳布桩位置;再根据水平位移和最大弯矩的计算结果,确定了最佳桩间距为6 m。最终得出4~#~6~#桩位组合的路基边坡最稳定,抗滑桩排距为6 m。In order to reasonably determine the anti slip pile support scheme for the roadbed bedding slope,fi-nite element software was used to analyze and determine the construction parameters.Based on the analysis and calculation results,it can be concluded that by comparing the maximum horizontal displacement of the slope with the safety factor calculation results,the#4 pile is determined as the optimal pile placement position;Com-paring the calculation results of horizontal displacement and maximum bending moment,the optimal pile spac-ing is determined to be 6 meters;Comparative analysis shows that the roadbed slope is most stable under the 4~6 combination,and the spacing of anti slip piles is determined to be 6 meters.
