摘要：

针对高陡边坡震致滑移条件下锚索系统无韧性、抗灾能力弱等问题，提出了一种板簧式减震锚头结构和实现方法。分析板簧锚头抗震工作程序并构建动力计算模型，对变形特性进行了解析；基于主要影响指标对板簧锚头作尺度分析，采用有限元程序获得板簧锚头抗震响应特征。研究表明：板簧锚头结构承载力和变形特性主要由片板长宽比、宽厚比、跨度和片板数决定，且对片板厚度最为敏感；激励峰值越大，其回弹恢复时间越短，整个过程能量耗散越多；本文优选尺度板簧锚头的地震响应傅里叶主频为14.73 Hz，抗震响应过程中发生往复变形及摩擦耗能以减轻地震冲击效应，具备良好的抗震性能和韧性，但应用设计时应综合考虑变形协调能力、耗能效果和经济性等因素。本文研究成果可为边坡锚索韧性组件结构的设计及应用提供理论依据和方法。

Abstract:

Aiming at the problems of non-toughness and weak disaster resistance of the anchor cable system under the condition of seismic slip on high and steep slopes， a leaf spring shock absorption anchor head structure and implementation method were proposed. The seismic working program of leaf spring anchor head was analyzed， a dynamic calculation model was constructed， and the deformation characteristics were analyzed. Based on the main influencing indicators， the scale analysis of the leaf spring anchor head was carried out， and the seismic response characteristics of the leaf spring anchor head were obtained by finite element program. The results show that the bearing capacity and deformation characteristics of the leaf spring anchor head structure are mainly determined by the aspect ratio， width-thickness ratio， span and number of plates， and are most sensitive to the thickness of the plates. With the increase of excitation peaks， the shorter the recovery time of its springback， the more energy is dissipated throughout the process. The optimal scale leaf spring anchor head seismic response Fourier main frequency is 14.73Hz， reciprocating deformation and frictional energy loss occur during the seismic response process to reduce the seismic impact effect， with good seismic performance and toughness， but the application design should comprehensively consider the deformation coordination ability， energy dissipation effect and economic factors. The research results can provide a theoretical basis and method for the design and application of slope anchor cable toughness component structure.
