摘要
介绍了高墩连续梁桥的两类稳定问题,论述了第一类稳定问题和第二类稳定问题.根据有限元计算方法,对新疆赛里木湖到果子沟段为连续梁桥的多种工况的稳定性进行了全过程分析,并对分析结果进行了比较,得出的结论可供工程设计和施工参考.
Since high-strength material and thin wall structure are widely used now, the stability question become more and more important in the high pillar continuous bridge. Two issues related to the stability of high pillar continu- ous bridge are introduced and discussed. Based on finite element computational method,the entire process analysis to the Xinjiang Sailimu lake to Guozi ditch section for the continuous bridge many kinds of operating mode stability and the comparison to the analysis result have been carried on. The conclusion obtained may supply the engineering design and the construction reference.
