摘要
采用数值模拟的方法,从滑带分布、桩身弯矩、桩身位移三个方面研究了上覆荷载对坡体及支挡结构稳定性的影响。结果表明:在上覆荷载一定时,随着荷载位置距坡口线距离越远,坡体剪应变增量越小即滑动面位移量越小,但会导致滑体范围增大,抗滑桩桩身最大弯矩及桩身位移均呈逐步增大趋势;上覆荷载距坡口线较远时,滑坡的支挡强度要比上覆荷载距坡口线近时要大。
In this paper,the retaining structure is analyzed from three aspects with numerical simulation method,including slip distribution,pile moment and displacement.The results show that:when the overlying loads are constant,the farther the load position from the groove line,the smaller the shear strain increment of the slope that the smaller the sliding surface displacement,but will lead to the landslide range increased;and the maximum bending moment and displacement of anti-sliding pile body showed a trend of gradually increasing;when the overlying load is farther from the groove line,the landslide retaining strength is larger than that the overlying load is close from groove line.
