概要 使用两种应变率对正常固结的样本进行三轴压缩测试：1 分钟内 1% 应变和 500 分钟内 1% 应变。在一些测试中，应变率在剪切过程中发生变化。在样本中心测量孔隙压力，并研究内部水分迁移的可能影响。从慢应变速率到快应变速率，峰值剪切阻力增加了约 10%；在小应变下，电阻增加了 100%。阻力随着应变率的增加而增加：（1）在小应变下，由于有效应力方面的强度增加，以及（2）在大应变下，由于超孔隙压力降低。还包括对严重超固结样本进行测试的结果。内部水分重新分布控制了这些样本的行为。 Des echantillons 巩固了压缩三轴应用的双轴变形方面的规范：1% en une 分钟 et 1% en ...
Synopsis Normally consolidated specimens were tested in triaxial compression using two strain-rates: 1% strain in 1 minute and 1% strain in 500 minutes. In some tests, the rate-of-strain was changed during shear. Pore pressures were measured at the centre of the specimen, and the possible effects of internal moisture migration were studied. The peak shear resistance increased about 10% in passing from the slow to the fast strain-rate; at small strains, the resistance increased as much as 100%. The increase in resistance with increase in strain-rate resulted: (1) at small strains, from increased strength in terms of effective stress, and (2) at large strains, from decreased excess pore pressure. Results from tests upon heavily overconsolidated specimens are also included. Internal moisture redistribution controlled the behaviour of these specimens. Des echantillons consolides normalements ont ete soumis a des essais de compression triaxiale employant deux vitesses de deformation: 1% en une minute et 1% en ...
