近年来,随着国家基础建设的大量投入,我国高速公路的里程数大幅增加。预应力梁桥是高速公路上的一种重要桥型,为了更加严格的控制好梁板施工质量,越来越多的单位采用了桥梁梁板静载试验,比起成桥试验,检测成本经济,检测工期短,检测操作方法相对简单。本文以预应力混凝土空心板的结构静载试验中的极限荷载数值的计算过程为列,探讨了Dr.Bridge在桥梁梁板试验中的应用的。
In recent years, with the massive investment in national infrastructure, the mileage of our expressways has increased substantially. Prestressed girder bridge is an important type of bridge on the highway. In order to control the construction quality of the slab more strictly, more and more units adopt the static load test of bridge girder. Compared with the bridge test, the testing cost is economical. The testing Short duration, testing methods are relatively simple. In this paper, the calculation process of the ultimate load in the static load test of the prestressed concrete hollow slab is taken as the column, and the application of Dr.Bridge in the test of the bridge slab is discussed.
