摘要
结合目前抗滑工程设计现状及预应力锚索抗滑桩桩土相互作用的特征,引入接触单元并改进有限元FCEP2D软件进行计算,得到抗滑桩锚固段的受力、弯矩和位移规律;进而分析了不同预应力、不同滑坡推力工况下的抗滑效果,提出了预应力锚索抗滑桩的最佳预应力,对工程设计具有一定的指导意义.
Based on the design methods and the interaction characteristics of anti-slide pile and soil, a program of improved FEM with contact element is developed. A calculation model is set up to calculate the bending moment and displacements along the pile with different cable＇s prestresses and different thrusts. The optimum presstress is discussed, which is important for the landslide control.
