摘要
设计并实施了大粒径散体颗粒材料结构传力的定量实验,研究了散体材料结构中在不同边界条件下,力的扩散、荷载应力、自重应力的分布状况及沿深度的变化规律.并根据散体颗粒材料结构的力学特性,应用随机理论,探讨了不同于传统理念的新理论模型,所得结果对于岩土工程中散体材料结构工程均具有重要的参考价值.
Many experiments on the granular structure with large-diameter particles submitted to compressive loads were designed and carried out. By means of the ration experiments of force diffusion inside a granular system and the stochastic theory to investigate the collective responses of the piles in detail, the transmission models of the load stress and deadweight stress were discussed. These results are significant to problems in geotechnical engineering.
