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.

Abstract

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.
