摘　　要：为研究构造内隔板对斜拉桥索塔锚固区承载力的影响分析,文中以广中江高速公路西江水道桥及其足尺试验为案例,采用ABAQUS,建立设置不同数量及厚度的构造隔板索塔锚固区的有限元模型,分析其对斜拉桥索塔锚固区承载力的影响。结果表明,在斜拉桥索塔锚固区内增设隔板可有效提高其承载能力,且屈服强度和极限承载强度随着构造内隔板的厚度增大而一定程度地增大。In order to study the impact of intra-structural partitions on the anchorage zone of cable-stayed bridge towers,the finite element model of the anchorage zone of cable-stayed towers with different numbers and thicknesses of intra-structural partitions was established using ABAQUS with the engineering background of Xijiang Waterway Bridge of Guangzhongjiang Expressway and its foot-measurement test,and the impact of the effect of these partitions on the anchorage zone of cable-stayed bridge towers was analyzed.The results show that the addition of spacers in the anchorage zone of cable-stayed bridge towers can effectively improve their load carrying capacity,and the yield strength and ulti-mate load carrying strength increase uniformly to a certain extent with the increase of the thickness of the spacers in the structure.
