预应力混凝土空心板静载试验研究

Research on static load test of prestressed concrete hollow slab

为检验预应力混凝土空心板的设计参数和质量是否满足要求,文章对某桥的预应力空心板进行了静载试验,测试空心板在荷载作用下的工作性能,在试验的过程中运用了混凝土试块加载的方法,检验了空心板的应力和挠度,并和理论值相比较和研究,根据公路钢筋混凝土的设计规定,对该预应力空心板作出质量评估.

To test whether the design parameters and quality of prestressed concrete hollow slab meet the requirements,in this paper,a static load test was carried out on a prestressed hollow slab of a bridge to test the working performance of the hollow slab under load.During the test,the method of loading concrete test blocks was used to test the stress and deflection of the hollow slab.Compared with the theoretical value and research,according to the design regulations of the reinforced concrete of the highway,the quality evaluation of the prestressed hollow slab is made.
