A series of small-scale model tests were carried out to measure stresses developed in testing quartz sand bed during loading and the corresponding variation during unloading in glass cylinder and steel rectangular box. A new conceptual stress release model was proposed based on the model test results by considering the fundamental behavior of granular materials.
采用室内静力模型试验研究了某种石英砂的加卸载和应力释放特性，对比了在砝码加卸载条件下圆筒玻璃容器和矩形铁箱容器中砂中不同位置处的应力变化，明确了砂的加卸载应力变化规律，并在此基础上提出了针对砂土的摩擦型散粒体材料的应力释放模型。
