摘要
为了优化某路堑高边坡抗滑桩支护条件下的支护参数,本文基于Midas/GTS有限元软件对抗滑桩设置位置、长度及间距进行分析研究。结果表明:该高边坡抗滑桩最优设置位置为二级边坡处,边坡安全系数最高为1.28,此时边坡的最大总位移、水平位移及竖直位移最小;随着抗滑桩长度增大,边坡位移均减小,安全系数增大,增至20 m后变化速度均有所放缓,因此抗滑桩最优长度选取20 m。随着抗滑桩间距增大,边坡位移均增大,边坡安全系数减小,且变化幅度均有所放大;抗滑桩间距为4 m时,边坡位移及安全系数均较好,因此抗滑桩的最优间距选取4 m。
In order to optimize the supporting parameters of anti-slide pile in a high cutting slope,the position,length and spacing of anti-slide pile were analyzed based on Midas/GTS finite element software.The results show that the optimal position of the anti-slide pile is the secondary slope,the highest safety factor of the slope is 1.28,and the maximum total displacement,horizontal displacement and vertical displacement of the slope are the minimum.With the increase of the length of anti-slide pile,the slope displacement decreases and the safety factor increases,and the change speed slows down after increasing to 20 m.Therefore,the optimal length of anti-slide pile is 20 m.With the increase of anti-slide pile spacing,the slope displacement increases,and the slope safety factor decreases,and the variation range is amplified.When the spacing of anti-slide pile is 4 m,the slope displacement and safety factor are good,so the optimal spacing of anti-slide pile is 4 m.
