新华社贵阳9月27日电（记者 周芷若）索鞍是放置在悬索桥主塔顶部的部件，它"扛起"主缆，作为关键传力枢纽，其性能直接关系到桥梁安 全性和使用寿命。 位于贵州山区的花江峡谷大桥是一座大跨径钢桁梁悬索桥。传统铸造工艺生产的索鞍，单件重量达到上百吨，若将其吊装到距水面近800米高 的主塔顶部，需要动用超大吨位的吊装设备。 "要是在大江大河上的话，万吨浮吊可以说是想吊哪里就可以吊哪里，但在绵延不绝的山区、悬崖峭壁之间，大吨位的设备或材料运输极为不 便。"花江峡谷大桥项目总工程师刘豪说。 桥梁跨径越大，索鞍所承受的重量越大，花江峡谷大桥的索鞍，需兼顾轻量化与高性能，因此，更轻、更强的索鞍成为技术突破要点。 建设团队首创了一种"高性能锻焊组合式索鞍"。这种锻造工艺的索鞍，与传统铸造索鞍相比，不仅在用料上减少了31%的用钢量，力学性能 和稳定性还有很大提升。"这是我们'被逼出来的技术'。"刘豪说。 6月6日，工人在贵州花江峡谷大桥桥塔顶上施工（无人机照片）。新华社记者 杨文斌 摄 他介绍，行业内最多进行厚度为200毫米的锻件焊接，而在此次建设中，为了一次成功焊接好厚度近500毫米的锻件，建设团队发明了一种自 动焊接设备，不 ...
