Symbolic stat analysis to physical and mechanic parameters of loose earth in Chongqing reservoir
Tang Hong · 2001
On the basis of testing in Lab to loose earth in Chongqing reservoir,the authors present probability analysis of earth characteristics including physical and mechanic parameters,then propose and test the distributions of the characters.The results verify that interior friction angle φ obeys logarithm normal distribution while cohesion c,unit weight r and water ω obey normal distribution.Therefore,sensitive parameters testing in Lab are reliable.
