万家寨水利枢纽黄河人行索桥是枢纽工程的临时建筑物,存在主索设计参数不详、锚具为缆机临时锚固方式等关键问题。通过索桥主索安全性检测分析结合新制OVM钢丝绳锚具配套试验等加固设计分析,在原锚锭基础上采用OVM钢丝绳锚具进行锚锭加固,保证索桥维持设计荷载标准继续安全使用。
The Wanjiazhai Water Control Project Yellow River pedestrian bridge is a temporary structure of the hub project. There are some key issues such as unknown design parameters of the main cable and temporary anchoring of the cable anchor. Based on the reinforcement design and analysis of the main rope safety test of the cable bridge and the supporting test of the new OVM wire rope anchorage, the OVM wire rope anchor is used to reinforce the anchor ingot so as to ensure that the cable bridge can maintain the designed load standard and continue to be used safely.
