摘要 通过理论计算,对韩江特大桥V形墩斜腿支撑体系进行优化设计,介绍了采用无平衡塔架且不设斜腿内置劲性骨架,仅以精轧螺纹钢水平对拉杆和型钢为主要支撑材料的施工工艺。该方案比优化前节约大量资金。 Through theoretical calculation, the design of slanted strut system of V-shaped piers of Hanjiang River Bridge was optimized. Unbalanced gantry was adopted and no rigid skeleton was set inside slanted legs. Only finish rolling rebar tension rod and profiled steel were adopted as the major supporting material. The optimized construction technology saved 1.6 million RMB, compared with the former program.
