简支空心板桥静力荷载横向分布理论与试验研究

静力荷载横向分布特性是简支空心板桥设计、检测中的一项重要性能参数。基于有限元方法的基本原理，形成了该类桥梁结构荷载横向分布特性计算的数值方法，该计算方法可以考虑桥面铺装对荷载横向分布的影响。以一座16m跨径的简支空心板桥为工程依托，采用静载试验方法测试了依托工程的荷载横向分布特性。把数值计算方法的计算结果同传统的铰接板法的计算结果以及实测结果进行比较分析，充分验证了本文提出的数值计算方法的可靠性和准确性。

Theory of Static Load Lateral Distribution and Experimental Study on Simply Supported Hollow Slab Bridge

Static load lateral distribution is an important parameter in the design and detection of the simply supported hollow slab bridge. Based on the fundamental of the finite element method, the numerical calculation method that can also take the effects of bridge deck pavement into consideration is presented for the load lateral distribution of this kind of bridge. Relying on a practical project of a simply supported hollow slab bridge with the span of 16 meters, the load lateral distribution is measured by static test, By comparing the numerical results with the calculation results by means of traditional articulated plate method, the reliability and accuracy of the proposed method is abundantly verified.
