摘　　要：建筑物从低阶地向高阶地扩展是建设工程发展的必然趋势,在大厚度湿陷性黄土场地的地基基础设计中,面临着缺少经验、按常规设计思路不能满足规范要求等问题。分析认为大厚度湿陷性黄土场地应注重考虑工程场地的水环境和基底下土层的具体状况,当能确定通过一定的排水措施和防水措施可以避免黄土浸水湿陷时,可以以防水措施为主设计地基基础,选用合理的地基基础型式和地基处理深度。同时结合实际工程加以分析,阐述大厚度湿陷性黄土场地地基基础设计的思路。Go with the development of construction,buildings expand from low terrace to high terrace is the inevitable trend.But it lacks of experience and conventional designs can't meet code in the foundation designs of collapse loess with large thickness.It should pay attention to the water environment and the specific conditions of the basement,using waterproofing measures mainly,and selects reasonable foundation and foundation treatment depth if simple drainage and waterproofing measures can avoid loess collapsing.In the end,the ideas of foundation design of collapse loess with large thickness combined with practical engineering is explained.
