CRS試験結果により試料の圧密係数の評定発表情報：Geomechanics and Engineering, Techno Press 巻: 5 号: 1 ページ: 57-70キーワード：
CRS試験、圧密係数、粘土概要：抄録：Constant rate of strain (CRS) consolidation tests were conducted for undisturbed Ariake clay samples from three boreholes in Saga Plain of Kyushu Island, Japan. The coefficients of consolidation (cv) were interpreted from the CRS test results by small- and large-strain theory. Large-strain theory was found to interpret smaller cv values and less strain rate effect on cv than that by small-strain theory. Comparing the theoretical strain distributions within a soil specimen to those obtained by numerical simulation shows that the small-strain theory can be used only for small strain rate, and the large-strain theory can be used for a larger range of strain rates.英語フィールド
