西禹高速公路留芳沟桥承载能力检测与评估

Examination and Evaluation of Bearing Capacity of Liufanggou Bridge of Xi'an-Yumenkou Expressway

西禹高速公路留芳沟桥梁体存在较多裂缝,属于病害桥梁。文中应用无损检测和静载试验来确定桥梁的实际承载能力。检测结果表明该桥有效预应力不足,需进行加固处理。

Liufanggou bridge girder of Xi＇an-Yumenkou Expressway has many cracks, belonging to diseased bridge. This paper adopts non-destructive examination and static loading test to determine the actual bearing capacity of bridge. The result indicates that this bridge has insufficient effective pre-stress and requires reinforcement treatment.
