湿陷性黄土地基处理

Ground treatment in collapsible loess region

湿陷性黄土的湿陷变形是影响地基稳定性的一个重要因素.从湿陷性黄土的工程地质特点入手,介绍了湿陷性黄土的两种分类及其各自特点和对建筑物稳定性的影响;分析了对湿陷性黄土地基处理不当在工程中容易出现的“弹簧土”现象,并对“弹簧土”现象的产生做了力学分析;阐述了湿陷性黄土地基处理的原理和方法;以实际工业废水处理工程总结了处理此类问题的经验.可供工程技术人员设计、施工时参考.

The collapsible deformation of collapsible loess is a very importance factors to the ground stability .This article begins with the characters of the collapsible loess, introduces two kinds of the collapsible loess and their characters and hazard to the fabric, analyzes how to recur the “spring soil” when it is wrong to the ground treatment ,further analyzes the “spring soil” in rock and soil mechanics; discuss the methods of the ground treatment in the collapsible loess region. As the example of one engineering , takes forward the plan for it. These results can be referenced to by engineering technical personnel in design and econtruction.
