摘要
颗粒介质广泛存在于自然界和工程领域,研究其抗拔摩擦力对于优化工程结构设计、确保工程安全具有重要价值.本文系统地探究颗粒介质中棒体受抗拔摩擦力与填埋深度、棒径的规律,并利用Janssen模型对实验结果进行模拟,理论模拟与实验测量符合得较好.
Study on resistant-drawn force in granular material has important theory meaning and practical value for optimizing engineering design and guaranteeing project safe operation.In this paper,the relationships between the resistant-drawn force and the imbedded height for different pile-diameters calculated from Janssen theoretic model is found to agree well with the test data.
