摘　　要：本文以某景区人行索道桥为例,应用MIDAS/Civil建立单根主缆模型,研究了不同垂跨比下主缆内力的变化规律,通过对轻型桥台的地基承载力、基底偏心距和基础稳定性进行验算分析,对比论证抗拔锚杆对人行索道桥轻型桥台的平衡稳定作用,相关结论可为同类型桥梁的设计研究提供一定的参考价值。Taking a scenic pedestrian ropeway bridge as an example,this study uses MIDAS/Civil to establish a single main cable model,studies the change pattern of the internal force of the main cable under different vertical span ratios,compares and demonstrates the balanced and stabilizing effect of the anti-pull anchor pile on the light abutment of pedestrian ropeway bridge by the checking computations and analysis of the foundation bearing capacity,the base eccentricity and the foundation stability of the light abutment,and the relevant conclusions can provide certain reference value for the design and research of the same type of bridge.
