: 1.想請教第三題中的孔隙比如何推求？

: 2.第二題中比重怎麼推都推不出2.58
: 想請教如何算？

: 想請教版上神人 因實在想不出來故發問請教
(3)
γm = [(Gs+S*e)/(1+e)]*γw
Gs*w = S*e
γm = [(Gs+Gs*w)/(1+e)]*γw
17.17 = [(2.6+2.6*0.086)/(1+e)]*1*9.81
e = 0.61
Dr = (emax-e)/(emax-emin) = (0.642-0.61)/(0.642-0.462) = 0.0178 = 17.8%
(2)
γm = [(Gs+S*e)/(1+e)]*γw
Gs*w = S*e
1.96 = [(Gs + e)/(1+e)] *1
Gs*0.25 = 1*e
1.96 = [(Gs + 0.25Gs)/(1+0.25Gs)]*1
Gs = 2.58
