用扁铲侧胀试验求解昆明地区土体的不排水抗剪强度

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.
