北京某工程杂填土地基处理技术研究

Research on the Ground Treatment of Miscellaneous Fill Based on an Engineering Project in Beijing

杂填土回填地基,均匀性较差、承载力较低、可压缩性较大、具有湿陷性和负摩阻力等危害,必须经有效地基处理后方可为建筑物所使用。结合北京某工程实例,对杂填土地基危害进行了分析,结合具体地基处理案例,详细介绍设计计算与施工方法。

The foundation has unfavorable factors of poor uniformity,low bearing capacity,large compressibility,collapsibility and negative frictional resistance,etc. backfilled with miscellaneous,which should be used for buildings though the efficacious foundation treatment. This article analyzed the harm of miscellaneous fill based on a project example in Beijing,combined with concrete foundation treatment case,described in detail the design,calculation and construction methods.
