摘要
分别按照第一类稳定和第二类稳定的稳定计算方法,分析了某引桥各空心高墩的稳定性系数,并分别考虑了截面形式为矩形和圆形的情况。研究结果表明:第一类稳定系数远远大于第二类稳定系数,墩高越高其稳定系数越小,随着墩的高度的增加,两种不同分析方法计算分析得到的稳定系数有下降的趋势,建议对空心高墩稳定性分析采取第二类稳定分析。
The stability coefficient of each hollow high pier of a bridge is analyzed respectively according to the stability calculation methods for the stabilities of the first and second kind, and the situation that the section forms are rectangle and round is considered respectively. The research result shows that the stability coefficient of the first kind is far larger than that of the second kind. The higher the pier is, the smaller the stability coefficient is. With the increase of the pier~ height, the stability coefficient acquired by the calculation analysis of two different analytical methods has a declining trend, and the stability analysis of the second kind is suggested to be adopted.
