随着我国经济的快速发展,使地方道路的分布越来越密集,修建高速公路时需要频繁地跨越地方道路以及河流等,尤其在水网密布地区,这种情况更加严重。而被跨越的道路、河流等和路线的交角可能差异很大,造成工程建设中较多地采用异型板梁结构。因此,研究异型铰接板梁的横向系数计算方法具有一定的现实意义。在进行合理假定的基础上,采用铰接板梁法推导出异型铰接板梁的横向分布系数的计算公式,总结了荷载在异型空心板梁上的横向分布规律,为异型铰接板梁的横向分布系数计算提供了理论基础。
With the rapid economic development in our country, local roads are becoming more and more densely distributed. It is necessary to frequently cross the local roads and rivers during the construction of expressways, especially in densely-covered water networks. However, the crossing angles of the roads, rivers, etc. that are crossed may be quite different, resulting in the use of shaped plate and beam structures more in the construction of the project. Therefore, it is of practical significance to study the method of calculating the transverse factor of profiled hinge plate girders. On the basis of reasonable assumption, the formula of transverse distribution coefficient of profiled hinge plate girder is deduced by the method of hinge plate and beam. The horizontal distribution of load on the profiled hollow plate girder is summarized, which is the horizontal distribution coefficient Calculations provide the theoretical basis.
