摘    要:湿陷性黄土场地的湿陷性质、类型评定与侧限浸水压缩试验的测试压力关系密切.考虑地区、基础型式、埋深和应力扩散的综合影响,确定湿陷系数测试压力,为准确确定地基的湿陷量提供依据.通过兰州两处高坪8个不同位置的湿陷性黄土的室内湿陷性试验,分析黄土密度、含水量、湿陷系数沿深度的变化规律.针对中小型建筑工程采用条形基础时,考虑3个不同基底压力在地基中的附加应力扩散规律,探讨饱和黄土地基总应力沿深度的变化规律,给出不同深度的黄土湿陷系数的浸水压力的建议值表.

关 键 词:黄土  湿陷系数  湿陷压力  室内试验

Abstract:The collapsibility of collapsible loess site and the assessment of its variety were closely related to the inundation pressure measured in the side-limited inundation compression test.The determination of collapsibility with the tested inundation pressure was conducted with the consideration of the combined influence of the region,foundation,embedment depth,and stress diffusion on it,providing a basis for its accurate determination.On the basis of indoor test of physical indices of collapsible loess taken f...
Keywords:loess  collapsibility coefficient  collapse pressure  indoor test
