摘要
依托京沈高速公路加宽改扩建项目的前期研究课题,对拼宽桥梁的超载状态进行了结构分析和理论研究,通过设定不同的拼接梁高,进行理论计算,得出结论,为高速公路改扩建工程提供理论依据。
Abstract According to preliminary research of reconstruction and extension project of Shenyang highway widening, we conduct structural analysis and the theoretical research to the overloading condition of the bridge widening. By setting different height of joggle beams, we conduct theoretical calculation and make a conclusion to give a theoretical basis for the highway re, cnnstruntinn and a-,rt^n~; ;~ot
