摘　　要：本文探讨如何正确理解、运用鲍罗米公式和混凝土基础理论,结合数理统计技术,进行预拌混凝土备用配合比设计,对比和分析了备用配合比的技术经济效果,确保在满足≥95%混凝土强度保证率的前提下,设计出经济合理的备用配合比。The thesis is to discuss conducting selection of backup mix proportions of ready-mixed concrete based on statistical techniques, correct knowledge and understandings about Bolomey equation and concrete basic theories. It is to make sure that the final backup mix proportions are reasonably economical under the precondition of 95% probability above design strength.
