摘要
以某跨径组合为(65+3×110+65)m预应力混凝土连续刚构桥为例,基于Midas Civil有限元分析软件,对比分析了合龙顺序对多跨连续刚构桥结构受力和位移的影响,结果表明,合龙顺序对多跨连续刚构桥运营阶段(10年收缩徐变)位移影响明显,但对最大压应力影响较小。
The paper rely on the（65 ＋ 3 × 110 ＋65） meter prestressed concrete continuous rigid frame bridge as engineering background. Based on the finite element analysis software Midas Civil, analyzed the influence of different closure schemeon the structure stress and displacement. The results show that different closure scheme have a great influence on displacement but less influence on the maximum compressive stress.
