桥梁用预应力混凝土空心板荷载试验

Load Experiment of Prestressed Hollow Concrete Plank Using in Bridge

对某桥梁用预应力混凝土空心板进行了静力有限元分行及荷载试验,结果表明在设计使用荷载作用下该空心板具有较高的安全裕度。同时该空心板满足《公路钢筋混凝土及预应力混凝土桥涵设计规范JTGD62—2004》和《公路旧桥承载能力鉴定方法(试行)1988)》要求,可以用于指定桥梁的建设或维修。使用的荷载试验方法简单易行,可供类似试验借鉴。

The static finite analysis and load experiment of a prestressed hollow concrete plank using in bridge were carried out in this text. And the result proves that the plank has a high safety abundance in the designed load. At the same time the plank meets the code for design of highway reinforced concrete and pretressed concrete bridges and Culverts JTG D62-2004 and The Method of Measuring and Evaluating of the Loading Capacity on the Highway Old Bridge （try a line）1988, so it can be used in building or maintenance of the given bridge. The method of load experiment in the text is simple and easy in using. And it can be used for reference to expert in the similar experiment.
