摘要
湘北红层残积土具有特殊的工程地质特性,作为基础持力层时,其指标选择存在不小难度。通过工程实测资料分析,对红层残积土地基承载力的确定及变形特征进行了讨论,提出了确定红层残积土地基承载力和变形模量的方法。
Residual soils of red beds in north Hunan Province exhibit special engineering geologic behaviors.There are many difficulties in the selection of mechanical indexes when they are used as supporting course.Based on analyses of measured data,the determination of bearing capacity and deformation characteristics of these soils acting as subgrade are discussed.The evaluation methods for the bearing capacity of this kind of foundation and deformation modulus are also suggested.
