强夯法处理湿陷性黄土地基的研究

Research on the Treatment of Collapsible Loess Foundation by Dynamic Consolidation

结合某电厂工程,对采用强夯法提高地基土承载力、消除湿陷性黄土的适用性试验研究,通过现场有效的质量控制,采用平板载荷试验、钻探与取样、井探、标准贯入试验、室内土工试验方法进行检测评价对比,在一定深度内能够有效提高复合地基的承载力并消除其湿陷性,更趋经济合理,具有推广价值。

Combine with the engineering of a power plant,the paper has carried out experimental study for enhancingthe bearing capacity and eliminating the collapsibility of the loess by adopt dynamic consolidation.By means ofeffective quality control in site,has made deter mination evaluation comparison by adopting the test method of platebearing teat,drilling sampling,exploratory shaft sinking,standard penetration test and soil test indoor,it be able toeffective enhance the foundation bearing capacity and eliminate collapsibility in certainly depth.It tends towardseconomics reasonable,it has promotional value.
