摘要

利用离散元法和光弹性实验，从介观尺度研究了颗粒在受限边界内的力链分布。分别考虑了刚性挡土墙的平行和收敛旋转模式。对挡土墙两侧颗粒的位移场和内应力状态进行了监测。结果表明，挡土墙上的侧压力呈非线性分布。在挡土墙引起的侧向荷载作用下，挡土墙内的颗粒由于位移场的差异而分为滑动区和稳定区。

On response of laterally loaded granules within retaining structure

Force chain distribution of particles within confined limited-boundary is studied in terms of mesoscopic scale with discrete element method and photoelastic experiments. The parallel and converge rotation pattens of rigid retaining walls are taken into consideration respectively. The displacement field and internal stress state of granular particles on both sides of the retaining walls are monitored. Results show that lateral pressure on retaining wall distributes nonlinearly. Subjecting to the lateral load induced by retaining wall, the particles within it are divided into sliding and stable zones due to discrepancy in displacement field.

期刊介绍： Although many phenomena observed in granular materials are still not yet fully understood, important contributions have been made to further our understanding using modern tools from statistical mechanics, micro-mechanics, and computational science. These modern tools apply to disordered systems, phase transitions, instabilities or intermittent behavior and the performance of discrete particle simulations. >> Until now, however, many of these results were only to be found scattered throughout the literature. Physicists are often unaware of the theories and results published by engineers or other fields - and vice versa. The journal Granular Matter thus serves as an interdisciplinary platform of communication among researchers of various disciplines who are involved in the basic research on granular media. It helps to establish a common language and gather articles under one single roof that up to now have been spread over many journals in a variety of fields. Notwithstanding, highly applied or technical work is beyond the scope of this journal.
