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 ...

转自：北京日报客户端 那年今日 巍巍钱塘潮，壮哉中华魂。1937年7月7日，"七七事变"爆发。两个多月后的 9月26日，我国第一座完全 由国人自主设计、施工的现代化大桥——钱塘江大桥正式通车。 然而谁也想不到的是，这座大桥在设计之初，便预留了一个放置炸药的长方形空洞，为的就是战争爆发 时能够将大桥彻底炸毁，不给敌人留下使用的余地。 令人痛心的是，预想竟真的成了现实。仅仅竣工89天后，为了防止日军利用大桥运输兵力物资，设计师 茅以升亲手炸毁了这座倾注自己心血的桥梁，"就好比必须亲自捏死自己的儿子一般。" "抗战必胜，此桥必复"，茅以升含泪写下了八个大字。多年以后，虽身不在杭州，但茅以升始终心系钱 塘江大桥。在他的推动下，历经7年修复，1953年9月钱塘江大桥终于全面通车，茅以升当年"不复原桥 不丈夫"的誓言终于变成现实。今天，北京日报客户端通过一篇长文，回顾钱塘江大桥的修建历程，再 现那些悲壮与辉煌同在的历史片段。 杭州钱塘潮头，六和塔前，钱塘江大桥默然伫立了近九十年，宛如长虹横卧。 今天，与它一般横跨钱塘江、担负人们日常通行的桥，杭州境内已有十座。然而，这座年岁最长、起于 战火烽烟之中的大桥，始终是杭州老百姓 ...
