本文探讨了在地震多发环境下锚固对于用来稳固干燥均匀填土边坡的重力式挡土墙的有效性。按极限平衡法计算的设计屈服加速度对研究的两种稳定措施都有效。地震引起的位移采用运动方程的滑块公式计算。现有的公式考虑了沿重力式挡土墙基底的滑动破坏和墙后主动楔形土体的转动破坏以及锚固边坡滑体的转动破坏。对于研究的填土边坡和输入的水平地面运动的特点,锚杆加固边坡在坡顶由地震引起的垂直和水平地震位移分别比在重力式挡土墙后主动楔形体顶部估算的垂直和水平变形小12%和32%。
This paper discusses the effectiveness of anchoring for gravity retaining walls that are used to solidify and dry uniform fill slopes in earthquake-prone environments. Design yield acceleration calculated by the limit equilibrium method is valid for both stability measures studied. Earthquake-induced displacements are calculated using the slider equation of the equation of motion. The existing formulas take into account the sliding failure along the gravity retaining wall basement and the rotational failure of the active wedge-shaped soil body behind the wall and the rotation failure of the sliding body on the anchored slope. For the study of fill slope and input horizontal ground motion, the vertical and horizontal seismic displacements caused by the earthquake on the slope roof of the anchor reinforcement slope are respectively less than those estimated at the top of the active wedge behind the gravity retaining wall Horizontal deformation is 12% smaller and 32%.
