【摘要】 传统框架锚固结构为刚性设计,在地震作用下框架梁与锚索支座连接部位及锚头易破坏失效。对此,根据"刚柔结合"的抗震思路及边坡—支护"共同承载"的思路,释放锚固支座与框架梁处的自由度,将刚性变为柔性铰接支护体系,利用Flac3D进行数值模拟,并对比了柔性与刚性支护体系下的边坡状态。结果表明,柔性框架锚固支护可有效控制边坡滑动并改善内力状态。新的柔性铰接框架锚固支护体系为边坡加固提供了新思路。更多还原

【Abstract】 The frame anchoring structure is always in the rigid stress state in the traditional design,the joint between the frame and the anchor cable is prone to be destroyed by the earthquake action.Therefore,according to the flexible-rigid model and the idea of "slope-support sharing the load",the freedom degree of anchoring support and the frame beam is released.Then,a new flexible hinged support system is proposed.Based on the numerical simulation by Flac3 D,the slope state under the flexible and rigid support system is compared.The results show that the flexible frame anchoring support can effectively control the slope sliding and improve the stress state.This new flexible hinged frame anchoring support system provides new ideas for slope reinforcement.更多还原
