某跨径布置为70m+90m+70m 3跨下承式钢管混凝土系杆拱桥钢管内部混凝土脱空现象严重,中孔左侧5号吊杆被撞导致PE+PU钢丝束护套撕落,吊杆高强钢丝裸露,给桥梁的安全造成极大隐患。本文主要针对该3跨系杆拱桥静载试验结果进行分析,评价其承载能力,并给出病害处治建议供同类桥进行借鉴和参考。
A span of 70m +90 m +70 m 3 spanning steel-tube concrete tied arch bridge concrete inside the concrete emptying phenomenon is serious, on the left side of the hole in the No. 5 boom collided lead PE + PU steel sheath tear, hanging High-strength steel bare bar, to the safety of the bridge caused great hidden danger. This paper mainly analyzes the static load test results of the 3-T tied arch bridge, evaluates its bearing capacity, and gives suggestions on disease treatment for similar bridges for reference.
