土壤老化。它们的工程性能通常在工程师实际感兴趣的老化时间期间显着改善。本文提供了研究和实践中的实例。它包括三轴IDS测试的审查，其次是它的使用，以avigage的问题，无论是老化改善摩擦或凝聚力的影响。与大多数当前的想法相反，土壤硬化和加固似乎完全是摩擦效应。所描述的老化效应表现为机械性的，这是由于在排水条件下分散的颗粒运动和内部应力的增加。本文最后提出了在实践中使用这些机械老化效应的建议。
Soils age. Their engineering properties often improve significantly during aging times of practical interest to engineers. This paper provides examples from research and practice. It includes a review of the triaxial IDS test, followed by examples of its use to investigage the question of whether the aging improvements result from frictional or cohesive effects. Contrary to most current thinking, the soil stiffening and strengthening appears entirely frictional in effect. The aging effects described appear mechanical, resulting from dispersive particle movements and internal stress arching under drained conditions. The paper concludes with suggestions for using these mechanical aging effects in practice.
