【摘要】 颗粒介质已成为国内外科学研究的热点,其研究结果正在被逐渐推广应用到岩土工程中去。本文运用焦散线法和激光全息光弹法对受集中荷载作用的颗粒堆中力的分布进行了较为详细的实验研究,通过对实验数据的定量分析得知:与传统连续介质弹性理论所揭示的规律不同,堆积体内部力的传递与分布遵循抛物线型方程。所得结果对现实工程具有重要指导意义。更多还原

【Abstract】 In this article, the caustics method and holo-photoelasticity method are used to investigate the distribution of contact forces inside a pack of discrete square cells submitted to a compressive load. Our results demonstrate that the collective response of the pack contradicts the traditional elasticity theory predictions and supports a description by equations of the parabolic type. These results are significant to solve problems in soil mechanics.更多还原
