摘要
通过军山大桥主跨斜拉桥索塔锚固区上塔柱足尺模型试验的研究与分析 ,阐述了大吨位小半径环向预应力应用的实际效果 ,对试验和施工应用中的相关问题作了客观的论述 ,并提出了合理的建议 .
The prototype model experiment for the cable tower anchor zone of Jun shan cable stayed bridge with 460?m main span length is conducted.Moreover, the actual effect of application of large tonnage and small radius annular prestressed force is analyzed. The related problems in the experiment and construction are objectively discussed and some reasonable comments are finally presented.
