摘要
本文根据湿陷性黄土中桩侧和桩底均埋有测试元件的４根大直径扩底桩的现场实测数据，分析了浸水湿陷对桩垂直承载力的影响，得出了负摩阻力的变化规律，最后提出浸水湿陷全过程中大直径桩荷载传递机理的《三阶段分析法》。
Measurements were made for 4 large diameter cast-in-place belled piles in collapsible loesswith instruments on shafts and toes.Influences of immersion collapsibility on pile vertical bearingcapacity were analyzed.Law of variation in negative skin friction was obtained.A“3-stage method”foranalyzing load transfer mechanism of large diameter pile during time of immersion test is presented.
