| 摘 要： | 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 JTG D62-2004>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.

| Abstract: | 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 mainte... |
