| 摘 要： | 锚碇基础的稳定性在悬索桥建设中占有至关重要的地位。通过规范的相应公式计算了某锚碇沉井基础的抗滑、抗倾覆稳定性安全系数;通过Midas/GTS软件建立了锚碇沉井基础的三维非线性有限元计算模型,并基于有限元分析结果建立了相应的抗滑、抗倾覆稳定安全系数的计算公式,对该锚碇沉井基础的抗滑、抗倾覆稳定安全系数进行了计算。通过对比分析,指出了目前规范计算中存在的缺陷。 |

| Abstract: | The stability of anchor foundation in suspension bridge is very important.By the formula of criterion,the safety factors of the stability against sliding and overturning are computed for one anchor caisson foundation.Based on the soft Midas/GTS,the three-dimension finite element model of the anchor caisson foundation is founded.The corresponding formula of the stability against sliding and overturning are deduced by the results of FEM and the safety factors are computed.By comparing and analyzing,the drawbacks of criterion are indicated. |
| Keywords: | stability caisson foundation suspension bridge FEM |
