The larger the density, the lower the effective mean normal stress, the more dilative response is.
土的密度越大，有效平均正应力越低，土的剪胀性就越大。
As to the shear strength mobilized in drained test, both of these two components are related with the effective normal stress on the failure plane.
而在排水试验中，则这两部分强度均对应于破坏时的有效应力。
