摘要
锚碇作为悬索桥的主要承力结构物,它的稳定性是十分重要的。针对润扬大桥北锚碇基础,基于三维有限元仿真分析模型的计算成果,对锚碇基础抗滑移、抗倾覆稳定进行了计算分析。研究分析了基础前、后墙土体压力对锚碇基础稳定性的影响,并且分析了基底接触面摩擦强度指标对抗滑移稳定性的敏感程度。通过研究分析,得出了悬索桥锚碇基础稳定性分析的一些有益的结论。
As a main bearing structure of suspension bridges, the stability of anchor foundations is very important. For the north-anchor foundation of Runyang Bridge, the stabilities against sliding and overturning are analyzed from the computation output of three-dimension finite element simulation models. The effect of soil resistance of the front and the back of pits on the stability is analyzed. The sensitivity of stability against sliding of soil rubbing strength in the base of pits is viewed. By research, some beneficial results are obtained for the stability of anchor foundation of suspension bridges.
