摘要
黄鹤立交CD2号匝道桥是预应力混凝土曲线梁桥,其在运营的初期出现裂缝,通过荷载试验及设计校核分析了裂缝产生的原因,提出了切实可行的加固方案。加固后的计算与荷载试验表明桥梁能满足使用要求。
The Ramp Bridge CD2~# of Huanghe Interchange is a prestressed concrete continuous curved girder bridge. At the early stage of operation, cracks occurred in the Bridge. The causes of the cracks are analyzed on the basis of load tests and design check, and feasible strengthening schemes are prepared. The further calculations and load tests of the Bridge after strengthening indicate that the Bridge can satisfy the requirements for operation.
