在滑坡灾害防治措施中,经常采用预应力锚索、抗滑桩、格构梁等其中的几种结构进行组合,形成复合型结构.就现已在路堑边坡工程中使用的复合结构,即预应力锚索抗滑桩-格构梁结构,在以预应力锚索、抗滑桩、格构梁三者相互之间位移变形影响结构为研究前提,利用有限元软件ABAQUS进行数值模拟分析.计算结果对比得知:考虑三者变形协调条件下的复合结构能够使边坡的加固效果更好;通过改变格构梁上锚杆拉力值,结合格构梁对边坡的框箍作用,达到能够降低桩身弯矩并使得其分布更为合理的效果.

In the landslide disaster prevention measures, the prestressed anchor, pile, lattice beam and other structures are often combined to form a composite structure. For the prestressed anchor slide-resistant pile - lattice beam composite structure which has been used in cut slope engineering, with the study premise of the effect of displacement deformation of prestressed ancho, slide-resistant pile and lattice beam on the structure, this paper used the ABAQUS finite element software for numerical simulation analysis. The results contrast shows that: the composite structure considering the deformation coordination enables the slope reinforcement effect better; through changing the lattice beam bolt tension value and combining with the frame hoop function of lattice beam on slope, it can reduce the bending moment and make their distribution more reasonable.
