纳潮口大桥施工过程的仿真模型建立与分析

Building and Analysis of Simulation Model for the Construction Process for Xiamen-Nachaokou Bridge

纳潮口大桥为中承式钢箱提篮系杆拱桥,为了模拟施工过程中桩基、系杆和主拱的相互作用关系,用等效柔度的方法简化桩基模型,用滑动支座模拟系杆力的变化。经过对比分析,得出了相关结论,可为类似工程的建模和分析借鉴参考。

Xiamen-Naochaokou bridge is a steel box tied-arch bridge with a through type as basket handle. To simulate the interaction relationship for pile foundation, tie-bar and arch rib in construction process, the authors simplify the pile foundation using equivalent flexibility and simulate the change of tie-bar force using sliding support. The conclusive results are obtained through comparative analysis.
