主要探讨了群桩沉降计算的理论和方法,并以郑州至西安客运专线陕县特大桥为实例,对采用不同的计算方法、不同桩周负摩阻力、不同的黄土湿陷性深度的沉降计算结果进行对比分析,得出采用铁路桥规实体基础法得到的结果比较合理,可作为湿陷性黄土地区桩基沉降计算的推荐方法。

In this paper, the main theories and methods of calculating settlement of pile groups was discussed, the example of the Shanxian super major Bridge of Zhengzhou-Xi＇ an passenger dedicated line was taken, comparative analysis to the calculating results of settlement by different calculating methods, negative friction around the piles and collapsible depth was made, it was indicated that the equivalent deep foundation method by ＂Code for design on subsoil and foundation of railway bridge and culvert＂ is reasonable and can be recommended as the method for calculating settlement of bridge foundation in the collapsible loess.
