对常德地区的饱和粘性土试样进行了三轴不固结不排水剪切、固结不排水剪切和固结排水剪切试验,获得了该地区饱和粘性土三轴试验的抗剪强度指标,通过对强度指标的分析比较,得出三轴慢剪指标作为设计、施工参数更合理,为粘性土路基的设计和施工提供了依据。
Nine groups of saturated clay samples were chosen from the nine sites in Changde.After UU,CU and CD tests of the samples,the triaxial test data were obtained.Meanwhile,after comparing these data with UU test strength index,CU test strength index and CD test strength index respectively,some conclusions of using the clay as subsoil was provided,which is important for the design and construction of the road.
