几种特殊土地基的工程特性及地基处理
|
摘要
城市化和工业化进程的快速发展,使得土木工程向各种复杂地基条件的区域发展,特殊土地基的工程特性引起工程师的重视。总结了湿陷性黄土、液化土、盐渍土等几种山西地区常见的特殊土的重要工程性质,提出了相应的地基处理方法以及工程注意事项;最后针对山西采煤大省的特点,对老采空区上建(构)筑物基础的稳定性评价、勘察技术及处治技术进行了论述。
As the fast developing of civilization and industrialization in China as well as the rising of living standards in the world, more land is needed. Consequently, many soil deposits previously claimed to be unfit for residential housing and other construction projects are now being used. In this situation, the engineering properties of special soils are of importance, which has been noticed by civil engineers. Thusly, the most important engineer- ing properties of several typical special soils in Shanxi province of China, such as: collapsible loess, liquefaction soil, and salty soil are summarized. And also corresponding soil improvement methods and main construction points are proposed. To aim at the fact that Shanxi province is the base of coal mining for China, the stability of foundations above mine goaf, investigation of mine goaf and its treatment technique are discussed as well.
