摘　　要：针对新近堆积黄土(Q24→3)的特殊土质,分析了确定该类黄土地基承载力常用方法存在的问题以及承载力受多因素影响的特点。基于统计理论,以大量实测载荷试验数据为样本,统计了承载力与影响承载力物理指标之间的关系,建立了新近堆积黄土地基承载力的多因素综合计算方法。工程实例表明,应用该计算方法确定的地基承载力,相对误差小于5%,能满足公路建设的要求。According to the special soil quality of recently deposited loess soil, this paper analyzes the existing problems of commonly used methods in determining the foundation bearing capacity of recently deposited loess soil and the multiple factors that affect it. Based on statistical theory, the relationship between bearing capacity and the physical indices is examined by using samples of actual plate loading tests data, the multi-factorial calculating methods of foundation bearing capacity of recently deposited loess soil are given. Actual examples show that the relative error of this method is less than 5% , which can meet the demand of highway construction. 2 tabs, 8 refs.
