偏心卸料使筒仓仓壁受力不均,会给筒仓结构的使用带来安全隐患。分析了国内外筒仓偏心卸料研究现状。从试验、理论、数值模拟三个方面总结了筒仓偏心卸料的研究成果。提出了筒仓偏心卸料研究的不足,具体表现为大直径浅圆仓偏心卸料研究匮乏,现有规范中也缺少相关的计算公式。分析为以后的筒仓偏心卸料研究提供参考。
Off-center unloading the silo warehouse wall uneven force, will bring the security risks to the use of the silo structure. The status quo of silo eccentric discharge at home and abroad is analyzed. The research results of eccentric discharge of silos are summarized from the aspects of experiment, theory and numerical simulation. The shortcomings of the research on eccentric discharge of silo are put forward. The research shows that the research on eccentric discharge of large diameter shallow silo is scarce, and the relevant formulas are also lacking in the existing codes. The analysis provides reference for the future research on silo eccentric discharge.
