预应力斜交梁的受力性能试验研究

Experimental research of the force property of pre-stressed screw girder

介绍了预应力斜交空心板梁的荷载试验方法,并通过对试验结果的分析,对预制空心板梁进行了可靠性评价,结果表明,所试验的斜交梁具有足够的刚度和承载能力,满足桥梁正常使用状态要求。

It introduces the loading experiment method of pre-stressed screw hollow girder, and makes a reliability evaluation of hollow prefabricated girder through the analysis of experimental result. The result shows that the experimental screw girder possesses enough rigidness and load capacity and it can satisfy the requirements of the using of bridges.
