摘要
本文将膨胀土强烈的胀缩性、裂隙性、超固结性及强度衰减特性归结为膨胀吸力矛盾运动的特殊性,分析了吸力变化的各阶段对土的力学特性的影响,推导了表示湿胀和干缩的骨架应力方程,并以一简单的力学模型描述这些变化。
In this paper the characteristics such as the strong swell and shrinkage, cracking, overconsolidation and the weakening of strength are summed up to be the particularity of the contradictory movement of suction in swelling soil. On every stage, the effect of the variation of suction on the mechanical properties of soil is analysed. An equation expressing the skelton stress induced in wet-swell and dry-shrink is derived. All variations are described by a simple mechanical model.
