摘要
某水电站进厂公路线路跨鲁羌沟泥石流排导槽,设1座30 m预应力混凝土T梁桥。桥面高程为1325 m左右,桥宽10 m。由于大桥的跨径较大,设计、施工技术难度较大,为了减少不必要的加固、维修费用,确保交通基础设施的安全性能,现对桥梁结构物工作状态进行梁荷载试验检测。某水电站进场公路桥梁检测工作取得了满意的数据,做出了准确的评估,精确有效地评估桥梁的实际承载能力,具有社会经济价值。
A 30 m prestressed concrete T-beam bridge is set across the debris flow drainage channel of Luqiang gully on the access road of a hydropower station.The bridge deck elevation is about 1325 m and the bridge width is 10 m.Due to the large span of the bridge,the design and construction technology are difficult.In order to reduce unnecessary reinforcement and maintenance costs and ensure the safety performance of traffic infrastructure,the beam load test is carried out for the working state of the bridge structure.The inspection work of the bridge on the access road of a hydropower station has obtained satisfactory data and made an accurate evaluation.It can accurately and effectively evaluate the actual bearing capacity of the bridge,which has social and economic value.
