湿陷性黄土地基勘察
collapsible loess foundation investigation
shixionxing huangtu diji kaneha湿陷性黄土地墓勘察(eollapsible loessfoundation investigation)为湿陷性黄土地基上建筑物的设计和施工所进行的工程地质勘察。在一定压力下受水浸湿时，土的结构迅速破坏而发生显著下沉的黄土称湿陷性黄土。湿陷性黄土分为自重湿陷性黄土和非自重湿陷性黄土两类，前者在自重压力下受水浸湿即发生湿陷，后者在自重压力下浸湿不发生湿陷。 表征湿陷性黄土湿陷特征的指标是湿陷系数(占，)和湿陷起始压力。湿陷系数是在给定的压力下由浸水所造成的相对变形值，a:妻0.015为湿陷性黄土，占。<0.015为非湿陷性黄土。湿陷起始压力是黄土发生湿陷时的临界压力，其值可按压力和湿陷系数的关系曲线确定。 勘察工作除按一般地基土的勘察要求进行外，着重补充查明黄土层的分布、厚度、湿陷类型和程度，地下水水位随季节的变化幅度。勘探点间距按均质土考虑，要有一定数量的钻孔穿透湿陷性土层。勘察成果是为:地基基础的设计和施工提供有关参数，对地基的湿陷程度进行评价;当地下水位有可能上升并影响建筑物的安全时，还要提供土在饱和状态下的强度和变形参数。 (傅世法)
