摘　　要：湿陷性黄土场地上的基桩,在天然含水量状态下做单桩竖向抗压静载荷试验进行承载力验收时,试验最大加载值须根据设计(浸水状态)确定。论文分别对非自重湿陷性和自重湿陷性黄土场地上的基桩,在天然含水量状态下做单桩承载力试验时,对试验最大加载值的确定提出了计算方法。When accepting the bearing capacity of foundation pile in collapsible loess site by single pile vertical compressive static load test under natural water content state,the maximum load value of the test must be determined according to the design(immersion state).In this paper,the calculation method for determining the maximum test load value of foundation piles in collapsible loess with non-self-weight and self-weight under natural water content is presented respectively.

关 键 词：自重湿陷性黄土场地 非自重湿陷性黄土场地 单桩承载力特征值 单桩竖向抗压静载荷试验 最大加载值
