摘要
为了了解目前我国预应力混凝土连续箱梁的超方水平,对结构的计算检验提供参考,以两座预应力混凝土连续箱梁为工程背景,采用现场调查方法对箱梁混凝土超方问题进行了研究。调查研究得到了两座桥箱梁超方水平的概率和在箱梁横截面上的分布,并得出了箱梁混凝土超方水平和施工方法之间的关系。
In order to know about the surplus amount lever of prestressed concrete continuous box girders in our country at present and provide the reference for calculation and test of structure,based on the field survey,a study is made of the concrete surplus amount of the two prestressed concrete continuous box girders which are the background project.Through investigating detailedly,the probability of the surplus amount level of the two box girders and the distribution of surplus amount level all along the cross s...
