摘要
丰都长江二桥斜拉桥采用跨度布置为(70.5+215.5+680+245.5+70.5)m钢箱梁斜拉桥结构,索梁锚固结构采用锚拉板式锚固结构,为确保锚拉板结构的安全性,对其进行空间有限元分析,得到锚拉板各部位的应力情况以及分布规律,并根据分析结果进行结构优化。
The Changjiang River No. 2 Bridge in Fengdu is a steel box girder cable-stayed bridge with span of （70.5 ＋ 215.5 ＋ 680 ＋ 245.5 ＋ 70. 5 ） m. Anchor plate was adopted in the anchorage zone of steel box girder. The spatial finite element analysis was carried out to ensure the capacity of the anchor plate. The stress state and distribution law on the anchor plate were obtained, and the structure was optimized according to the results.
