摘　　要：以一座斜腿刚构桥为例 ,针对施工中遇到的高温合拢问题 ,对斜腿刚构桥的温度及混凝土收缩引起的次内力进行了分析研究 ,并对该类桥型的施工方案进行探讨 ,提出减小结构次内力的有效措施。Aiming at the question of high temperature closure in the construction of a rigid frame bridge with inclined legs, the second internal forces caused by the shrink of concrete and descent of temperature were studied. The construction scheme of this style bridge was discussed, and the effective methods to reduce the structural secondary internal forces were brought forward.

关 键 词：斜腿刚构桥 高温合扰 次内力分析 温度应力 控制 施工方法
