斜拉索在塔柱上的锚固区是将斜拉桥拉索承担的上部结构自重和外荷载传递到主塔的重要结构,确保斜拉索与主塔的锚固区的安全至关重要,也是斜拉桥成败的关键因素之一。以珠江黄埔大桥为依托,简要介绍了大桥索塔锚固区足尺节段模型试验的方案、过程和结果,同时还得出开裂荷载和极限承载荷载等重要结果。通过有限元分析将试验结果与数值分析结果进行比较,结果比较接近。
The anchorage zone of the stay cable in the tower is an important structure that transfers the deadweight of the superstructure and the outer load to the main tower that the cable stayed in and ensures the safety of the stay cable and the anchorage zone of the main tower. Cable-stayed bridge one of the key factors. Based on the Zhujiang Huangpu Bridge, the scheme, process and results of the full-scale model test of the pylon anchorage zone of the bridge are briefly introduced. At the same time, some important results such as cracking load and ultimate load are also obtained. Through the finite element analysis of the experimental results and numerical analysis results are compared, the results are relatively close.
