摘要
用非饱和土三轴仪和GDS应力路径三轴仪对兰州张家台变电站工地挤密桩复合地基桩间非饱和黄土和原状黄土进行系统的试验研究，通过同时控制吸力和净室压力的三轴排水剪切试验，分析探讨了挤密桩间黄土和原状饱和黄土的应力-应变性状及强度规律，得到了各自的变形和强度参数，并将这些参数进行了比较和分析，利用规范推荐的方法量化了灰土挤密桩对桩间非饱和黄土在地基承载力方面的改善作用。
This paper describes a triaxial testing of unsaturated soils apparatus modified by Cben Zbenghan for compacted loess and a triaxial testing on saturated soils for uneompaeted loess by GDS. The effects of compacting on stress - strain relation at different degrees of suction and confine press are discussed. Parameter of deformation and strength are obtained, compared and analyzed these parameters.
