以黄河上一座高墩预应力混凝土连续刚构桥为背景,重点探讨了该类桥梁中高墩的设计优化。通过对5种试验墩型对应结构的详细数值分析,分析比较了单箱墩与双薄壁墩在同一高墩中,以不同高度比例组合下的受力情况。
Based on a high pier prestressed concrete continuous rigid frame bridge on the Yellow River, the design optimization of high pier in such bridges is discussed. Through the detailed numerical analysis of the corresponding structures of five kinds of test piers, the stress conditions of single-box pier and double-thin-walled piers in the same high pier with different heights and proportions are analyzed and compared.
