纵目沟特大桥新型柱板式空心高墩设计

摘要

以黄陵—韩城—侯马铁路纵目沟特大桥主桥为背景，介绍一种105m墩高的新型柱板式空心墩。从主梁设计、桥墩设计构思、受力分析、试验研究方面进行研究。计算结果表明，柱板式空心墩各项指标均满足相关规范要求，克服了高烈度地震下黄土沟壑区桥梁设计的困难。%Based on Zongmugou extra-long bridge on Huangling-Hancheng-Houma railway, this paper introduces a new-type column plate hollow pier of 105m high, and studies the design of main girder, the concept of pier design and the test. The calculation results show that all indexes of the column plate hollow pier meet the relevant standards and the difficulties in the design of bridges in highly seismic region and gully region of loess are solved.
