| 摘 要： | 斜拉索与钢箱梁的锚固区是斜拉桥的关键部位,其结构和受力都相当复杂,一般的平面分析很难反映实际的应力分布.本文简要介绍了南京二桥锚箱模型试验,对锚箱及其附近腹板的应力大小和分布进行了研究,并对照有限元空间计算,得出了一些有益的结论.

| Abstract: | The anchorage of a cable with the beam is the key part in a cable?stayed bridge.The construction and the behavior of an anchorage zone are rather complicated.It is hardly to get the actual stress status by a general plane analysis.A model test of the second Yangtze river bridge at Nanjing is presented in the paper.We found that the stress in the front part of the anchorage zone is in compression.The behind part of the anchorage zone is subjected to a tension.The maximum value of web stress is located in the anchorage zone.The results of model test are compared with a space finite element analysis.Some useful conclusion is obtained from the test. |
