摘要
评价上海地区饱和软粘土的不排水抗剪强度。通过室内试验及十字板剪切试验得到的不排水抗剪强度cu 与用扁铲指数 (水平应力指数KD)计算得到的不排水抗剪强度cu 进行比较 ,说明Marchetti(1980 )计算cu 的公式适用于上海地区的饱和软粘土。同时 ,扁铲模量ED 与不排水抗剪强度cu 具有线性相关性 ,故找到了一个更为简便的计算不排水抗剪强度cu 的公式。
Through comparing the undrainde shear strength determined by laboratory tests with that by DMT horizontal stress index K D,make a conclusion that Marchetti's equations concerning the evaluation of undrained shear strength are applicable to soft cohesive soils in Shanghai district,and the dilatometer modulus E D has linear relativity with undrained shear strength.
