When the stress acted on concrete specimens exceed 60 % of ultimate compressive strength, the coefficient ( k ) will increase obviously but the largest change is still within the order of 10 - 9 cm / s. the time - dependant characteristic can be expressed by the function k = ( a + ct ) / ( l + bt ). the coefficient k decreased significantly in the first 40 ~ 60 hours of the water permeability test, and the decreasing rate became slow as the time goes on
混凝土的滲透穩定性則表現為滲透系數會隨滲透時間增加而減小，減小的趨勢是起初的40 60小時內下降最快，其後愈來愈平緩，其規律可用公式k = （ a + ct ） （ 1 + bt ）來表示。 -
