针对红岩滑坡双排抗滑桩施工过程中前、后排抗滑桩锚固深度的选取问题，基于 FLAC3D程序，建立简化的双排抗滑桩数值计算模型，考虑桩、土相互作用，通过在滑坡体边界施加位移的方法模拟作用在抗滑桩上的水平推力，对前排和后排抗滑桩锚固深度变化时双排抗滑桩侧向位移、弯矩、剪力和抗滑力的变化规律进行研究，研究发现，前排或后排抗滑桩锚固深度的变化对双排抗滑桩的侧向位移、弯矩、剪力和抗滑力有显著影响，且该影响与所施加的边界位移有关。

According to the problem of selection of anchorage depths of front-row and back-row piles in double-row anti-slide piles in Hongyan landslide project,a simplified calculation model is built based on the FLAC3D program. In this model,pile-soil interaction is considered by applying displacement on the boundary of sliding mass to simulate the horizontal thrust force acting on anti-slide piles. Based on this numerical model, variations of deflection,bending moment,shear force and sliding resistance of the double-row anti-slide piles are studied under different anchorage depths of the front-row and back-row anti-slide piles. It is found that the deflection,bending moment,shear force and sliding resistance are affected by the anchorage depths of the front-row and back-row anti-slide piles;what′s more,the affected degree is related to the values of displacement applied on the boundary of sliding mass.
