摘要
本文根据埋设测试元件的人工挖孔扩底桩基础现场静载试验 ,对黄土中端承于厚层非湿陷性黄土和卵石层的扩底桩竖向承载性状分别进行了讨论。分析了荷载传递规律和地基破坏模式 ,探讨了端承于土层时浸水饱和对侧阻和端阻的影响 。
Vertical bearing behaviour of belled pile ended in thick non\|collapsible loess and cobble are studied respectively herein based on field static load tests.Load transmission law and mode of foundation failure are analyzed.The effect of immersion on shaft resistance and tip resistance of the pile in saturated loess are also discussed and compared with the existing test results.
