| 摘 要： | 为判断北盘江大桥推荐桥位安龙岸边坡的稳定性，分别采用Slide. v6007、Phase2 V9. 0边坡稳定分析计算软件和FLAC3D软件对安龙岸边坡进行二维和三维稳定性计算分析。计算分析显示，安龙岸边坡稳定性计算安全系数大于安全系数设计标准，从理论分析来看该边坡处于稳定状态，并且有一定的安全裕度。相对于二维分析的计算安全系数，三维分析的计算安全系数要大。安龙岸边坡稳定性分析结论为花江北盘江大桥推荐桥位的初步设计提供了较为合理的依据。

| Abstract: | To judge the stability of the Anlong bank slope of the recommended position of Huajiang Beipanjiang bridge, FLAC3D software and slope stability analysis software Slide. v6007, Phase2 V9. 0 were used to analyze the two-dimensional and three-dimensional stability of the Anlong bank slope, respectively. The calculation and analysis show that the safety factor of Anlong bank slope stability calculation is greater than the design standard of safety factor. From the theoretical analysis, the slope is in a stable state with a certain safety margin. Compared with the calculated safety factor of two-dimensional analysis, the calculated safety factor of three-dimensional analysis was larger. The stability analysis conclusion of the Anlong bank slope provided a reasonable basis for the preliminary design of the recommended position of Huajiang Beipanjiang bridge. |
