摘    要：探讨了由南非引进的200/400kN(20/40t)快速让压水压支柱的支护能力,建立了与实际运用密切相关的支柱最小初撑力、工作阻力增量及额定工作阻力计算的数学模型,对水压支柱的试验及以后的推广使用具有重要的指导意义.

Abstract: This paper discusses the sustaining force of 200/400 kN (20/40 t)on rapid yield hydraulic props imported from South Africa. It establishes the mathematical models about the smallest early support force,the amount of increased support force and rated support force.These researches are very useful in the hydraulic prop's test and on spot worksites.
