摘要:
在综合分析抗滑桩受力特点,归纳总结多个工程经验的基础上,提出了h型抗滑桩的三种土压力模式;基于ANSYS软件建立有限元模型,分析矩形、三角形和梯形等三种土压力作用下h型桩的内力分布特点,同时考虑桩前滑体被动土压力作用对h型抗滑桩内力分布的影响;利用桩顶位移与桩体最大弯矩双控指标对h型抗滑桩的几何参数进行了优化. 结果表明:对于矩形截面h型桩,当前后桩间距取2.5~5倍桩截面宽度,连梁高度为1~2倍桩截面宽度,连梁刚度为桩身刚度的4~5倍时,桩身受力最为合理.
Abstract:
Three patterns of earth pressure on the h-type anti-sliding pile were proposed based on a comprehensive analysis of the forces acting on the piles and a summary of previous engineering experiences. The stress distribution of the h-type anti-sliding pile under rectangular, triangular, and trapezoid patterns of earth pressure was explored using a finite element model constructed by the ANSYS software, and the effect of the passive earth pressure in front of the piles was also taken into consideration. The displacement of pile top and the maximum bending moment of pile were used as double control index to optimize the geometric parameters of the h-type anti-sliding pile. The results suggest that the h-type anti-sliding pile with a rectangular cross section is subject to the most reasonable stress when the spacing between adjacent piles is 2.5-5 times the width of the pile cross section, the height of coupling beam is 1-2 times the width of the pile cross section, and the stiffness of cross beam is 4-5 times that of the pile.
