以临县黄河桥为工程实例,探讨了多孔大跨度连续刚构桥,通过采取改变合龙顺序、在合龙前施加水平顶推力等合龙措施,来控制和减小由降温和混凝土收缩、徐变引起的边墩墩顶位移过大对桥墩的不利影响。
Taking Linhe Yellow River Bridge as an example, the porous long-span continuous rigid frame bridge was discussed to control and reduce the shrinkage and creep caused by the cooling and concrete shrinking by adopting such measures as changing the closing sequence and applying horizontal pushing force before closing. Displacement of side piers is too large to adversely affect the piers.
