The Application of Models to Geotechnology

摘要: This chapter discusses the application of models to geotechnology. The exact reproduction full-scale conditions, or absolute similitude, is not achieved on a small-scale model. For this be possible, scales length, time, and pressure (or mass) must changed, without altering theoretical equations that describe behavior materials concerned. On such model, deformations would observed same scale as ratio stresses in model its prototype equal geometrical factor. A simple therefore, cannot reproduce detail rock soil structure under load. When loaded by forces gravity, generated own mass, it simpler gravitational body In case, from which constructed much softer less dense than those structure. If they are chosen way mechanical properties elastic, plastic, viscous deformation may deduced scaled measurements stresses, times, then said made equivalent materials.
