摘　　要：对自重湿陷性黄土场地中的2根灌注桩开展了浸水饱和状态下的水平向静载荷试验,结果表明:随着水平荷载的增加,桩身水平位移、相同荷载增量下的桩身位移增量及残余水平位移均增大。Field tests on 2 laterally loaded bored piles in self-weight collapsible loess site on condition that loess around pile was saturated were conducted. Test results show that with the increase of the lateral load,the horizontal displacement of pile shaft,the increment of the horizontal displacement corresponding to the same increment of the lateral load and the residual displacement of pile shaft increase.
