摘要
强夯是处理湿陷性黄土地基的一种有效方法。灵宝市委市政府办公大楼湿陷性黄土地基，经强夯处理后，地基土孔隙比和压缩系数降低，干密度提高，湿陷性被消除，地基承载力大幅度提高并满足了建筑设计基础底面压力２２０ｋＰａ／ｍ２的要求。
The powerful ramming is a effective method to deal with the foundation in wet collapsing loess.The foundation in wet collapsing loess of the office building of Lingbao municipal Party committee and municipal government has been compacted by powerful ramming later,the void ratio and compressibility factor of foundation soil have been depressed,the dry density has raised,the wet collapse has been removed.As a result,the bearing capacity of foundation has greatly raised and satisfied the demand which designed foundation sole pressure is 220kPa/m 2.
