随着现代科技的发展,桥梁设计趋向更为美观、经济合理,轻型墩台得到了广泛的应用.轻型墩台的柔性较大,各个墩台之间的相互作用也就尤为突出.因此,在计算墩台的内力时必须考虑它们的联合作用. 梁桥的联合抗推作用分析是一个很为复杂的问题,许多学者在这方面作了大量的探讨, With the development of modern science and technology, bridge design tends to be more aesthetically pleasing and economical, and the light piers have been widely used. The light piers are more flexible and the interaction between piers and abutments is more prominent. Therefore, When calculating the internal forces of piers and abutments, their joint action must be considered. The joint anti-push analysis of the beam bridge is a very complex issue. Many scholars have made a lot of discussions in this respect,
