Field measurement showed that the strain in most of geotechnical engi neering regions belongs to small strain.

岩土小应变情况下表现出许多与一般中大应变实验不同的特性。现场测试表明岩土工程中应变一般都比较小。因而近年来岩土小应变问题受到重视。本文对当前岩土小应变力学行为实验研究与本构模型研究进展进行了较为系统的描述。提出了合理描述岩土小应变力学特性需要进一步研究的几个问题。

An energy-injecting virtual-mass (EIVM) resonant column system was employed to investigate the small strain behavior of dry sand; and the effects of effective mean normal stress, density of soil samples, amplitude of shear strain, as well as number of loading cycles on shear modulus and damping ratio are studied. The test results show that the shear modulus increases with effective mean normal stress and soil density, while the damping ratio exhibits the opposite response. Moreover, the effects of effective mean normal stress on the small strain behavior of dry sand are more than those of soil density. As the shear strain increases, the shear modulus become smaller; but the damping ratio become larger. The number of loading cycles has no significant effects on shear modulus, but it influences the damping ratio to a quite extent.

>=A nano-composite model of filler-rubber system is proposed. Contrary to the well-known Einstein-Guth-Smallwood hydrodynamic model, which was developed from low filler loading then increased to a practical level, the proposed model starts with the maximum filler concentration. That is, the filler network junction width is initially zero, then "diluted" to an average width in order to ob tain the correct filler volume fraction.

>=A nano-composite model of filler-rubber system is proposed. Contrary to the well-known Einstein-Guth-Smallwood hydrodynamic model, which was developed from low filler loading then increased to a practical level, the proposed model starts with the maximum filler concentration. That is, the filler network junction width is initially zero, then "diluted" to an average width in order to ob tain the correct filler volume fraction. By assuming a simple cubic arrangement of the aggregates, the small strain behavior of the junction rubber is analyzed in extensional mode. Using only a few parameters from carbon black morphology, a formula for the filler loading effect on the Young's modulus is obtained with results similar to those from the hydrodynamic models. However, this is achieved without resorting to the "occluded rubber" correction factor. At small extensional strains, it is assumed that there is no slippage induced frictional energy loss on the filler surface. To account for the hysteresis, it is proposed instead to consider the friction between rubber molecular chains as a result of deformation and the boundary condition effect on the junction rubber. This model suggests that the hysteresis, tanδ, is inversely proportional to the average junction width of the filler network. Finally, the Payne effect with its various facets is discussed in terms of the network junction model, with results that are interesting and encouraging.

提出一种填充橡胶体系的纳米复合材料模型。在众所周知的Einstein-Guth-Smallwood流体动力学模型中,填料是从较低填充量开始,然后再增加到实际使用水平,与之不同,提出的模型一开始便使用最大填充量。也就是说,填料网络连接宽度开始为零,然后被“稀释”至平均宽度,以便获得准确的填料体积分数。假定聚集体为简单的立方体排列,以外延方式分析连接橡胶的小应变行为。利用仅有的几个根据炭黑形态学得到的参数,获得了填料填充量对杨氏模量影响的公式,结果与流体动力学模型的结果类似。但是获得这一结果没有凭借“吸附橡胶”修正因子。在小应变下,假定不存在导致填料表面摩擦能损耗的滑动。为了解释滞后损失,提出考虑因变形产生的橡胶分子链之间的摩擦和边界条件对连接橡胶的影响。该模型表明,滞后损失tanδ与填料网络的宽度成反比。
