摘　　要：目前对粗骨料级配搭配的优化主要以空隙率为评价指标。随着空隙率降低,可使得混凝土硬化体系更加均匀密实,增加强度,通过对当地地材级配的试验研究,调整粗骨料双级配配比,实现最佳粒径搭配,保证混凝土实体质量。Currently,the optimization of coarse aggregate gradation is mainly based on the evaluation index of porosity.As the porosity decreases,the concrete hardening system can become more uniform and dense,increasing strength.Through experimental research on the local material grading,the coarse aggregate double grading ratio can be adjusted to achieve the best particle size combination and ensure the quality of the concrete entity.

关 键 词：混凝土 粗骨料双级配 空隙率
