| 摘 要： | 结合西安市东二环—北二环立交工程,在自重湿陷性黄土场地上进行了钻孔灌注桩大型原位浸水载荷试验。通过对立交工程桩基未浸水、浸水前及浸水后三种工况的载荷试验,对桩基的极限承载力和沉降量进行对比研究,分析了桩基负摩阻力强度值及其分布规律,研究成果对黄土区域桥梁桩基础的设计和施工具有重要理论价值和指导意义。

| Abstract: | Combining with the interchange project of east second ring-north second ring in Xi＇an,in the collapsible loess sites,large-scale flooding load test of drilling pile was conducted.Through the load test on the three conditions of overpass project pile,flooding,before flooding and after flooding,comparative studied the ultimate bearing capacity and the settlement,analyzed the intensity value of negative friction and its distribution,research results provided important theoretical value and guide to design and construction of bridge piles in loess region. |
