马坡洛河特大桥刚构连续梁设计

Continuous Beam Design of Rigid Frame of the Mapoluo River Grand Bridge

包西铁路马坡洛河特大桥采用刚构连续梁的结构形式,空心高墩。详细介绍了上部结构构造、施工方法、静力计算等,结果表明,刚构连续组合在结构受力、使用功能和适应环境等方面均有一定的优越性。

The grand bridge spanning the Mapoluo River of Baotou-Xi＇ an railway uses the structure form of rigid frame continuous beam and high hollow pier. This paper introduces the upper structure formation, construction method, calculation of static force etc. The result shows that the steel frames has advantages in terms of structure stress, functions and ability to adjust to the environment.
