黄龙带特大桥桥侧护栏优化

Optimization of Roadside Barrier of Large-span Bridge for Huanglongdai Reservoir

为对黄龙带特大桥桥侧护栏进行优化,结合了前期研发的特高防护等级景观钢护栏成果,并对优化结构性能进行分析,结果表明:相比原设计方案优化结构的安全性能更高,工程适应性强,施工工艺更加简便,且材料用量更少,大大节省了工程造价,同时还具有更好的景观效果。可见该优化结构满足实际工程应用要求。

In order to optimize the roadside barrier of the large-span bridge for Huanglongdai Reservoir, and combined with achievements of the high-level protective steel landscape barrier researched and developed in the earlier stage, the performance of optimized structure is analyzed. The results show that the safety performance of the optimized structure is higher compared with the optimized structure of the original design scheme, its engineering applicability is strong, its construction technology is more convenient, and its material consumption is less, which greatly save the engineering cost and has the better landscape effect. Therefore,the optimization scheme can meet the demands of practical engineering applications.
