three-hinged arch bridge

Analysis and Experimental Study on Three-span Half-through Continuous Beam-arch Combination Bridge

中承式3跨连续梁拱组合式桥梁的分析和试验研究

Based on the similar simulation model experiment, the three forms of the bridge arch, semi_arch and pillar on the top coal caving and drawing characteristics are put forward.

运用相似材料模型试验，提出了顶煤冒放的桥拱式、半拱式和柱式3种结构特征；

The bridge applies the continuous girder with five spans and three arches ≠ the double-deck and overlap arch structure of tie bar combined system, which was applied firstly in China with high-technical content.

该桥主桥采用的五跨三拱连续梁&系杆拱组合体系的双层叠拱结构，为国内首次采用，技术含量较高。

Through comparative study of hingeless arch bridge 、 two-hinged arch bridge and three-hinged arch bridge, the influence of connection condition of arch on mechanical condition is discussed.

通过无铰拱、双铰拱、三铰拱的体系对比分析，讨论分析了拱自身连接条件对结构受力形态的影响；
