摘要
经验证,在利用扁铲侧胀试验(DMT)计算土体不排水抗剪强度Cu时,适合于上海地区的计算式,用于昆明地区时误差较大。参照昆明地区多个实际工程十字板剪切试验(VST)数据,对这些工程中的扁铲侧胀试验数据进行统计分析,得到了适宜于计算昆明地区土体不排水抗剪强度Cu的计算式。
It is certified that in the calculating of undrained shear strength of soil by using flat dilatometer test(DMT),the deviation is large when the formula of Shanghai is used in Kunming area.Refer to lots of vane shear test(VST) date of actual engineering in Kunming,the flat dilatometer test data is statistical analyzed.Then the formula of the undrained shear strength of soils is obtained,which is very applicable in Kunming area.
