宁县某工程场地黄土湿陷性研究

Study on Loess Collapsibility of an Engineering Site in Ning County

黄土湿陷性与黄土的物性指标有着密切关系。通过对宁县某工程场地黄土取样进行室内试验,对黄土湿陷性与深度、天然含水量、孔隙比、干密度、饱和度的关系进行了研究,并对场地黄土地基进行了湿陷性评价,获得了该地区的黄土湿陷性规律,为工程场地地基处理、设计及施工方案提供依据。

The collapsibility of loess is closely related to its physical properties.Based on the laboratory test of loess sampling in a project site of Ningxian County,the relationship between the collapsibility of loess and the depth,natu?ral moisture content,void ratio,dry density,saturation was studied,and the collapsibility of loess foundation was eval?uated.The collapsibility law of loess in this area was obtained,which provided the basis for the foundation treatment,design and construction scheme of the project site.
