某建筑场地地基土湿陷性的试验研究

关于黄土的湿陷性问题,前人所做的理论研究的工程实践已很多,已总结出有规律性的研究成果。但对个别地区、场地地基土湿陷性的异常情况,还需做专门的试验研究。本文通过对呼和浩特市区大青山前冲、洪积层湿陷性进行的试验研究,揭示了该地区表层冲、洪积层在浸水条件及荷载作用下正常压缩变形与湿陷变形的非常规关系,将研究结果应用于内蒙古经济管理干部学院二期建设工程,节省费用20余万元,并对该地区的进一步建设和开发起到了一定的指导作用。

The Test Research of Subsoil Collapsibility at Certain Building Sites

The problem of collapsible loess has long been studied in theoretical research and engineering practice,However,special test researches sho- uld be made for unusual conditions of subsoil collapsibility of specific regions and sites,This paper reveals the unusual relation of the normal compressive deformation with the collapse deformation of alluvial and diluvial soil of Daqing Mountain,lying in the north of Huhhot City, in a condition of inundation.The research results have been applied to the second stage construction project of Inner Mongolia Economic Manage- ment Institute for Cadres.This has helped save a cost about 200,000 yuan and give valuable guidance to the further construction in this region,
