摘　　要：本文主要梳理评价植生混凝土的相关规范及参考文献,调研总结植生混凝土技术的研究动态和实体工程配合比设计,植生混凝土的设计指标与力学性能关系,推荐配合比设计指标的设计区间;设计孔隙率应选择在0.21~0.30,最佳范围区间为0.25~0.28;水胶比的选取在0.275~0.32;平均骨料粒径的选择范围较广,粒径可选择8~30mm,最佳选择应在13.5~23mm。This paper has reviewed and evaluated standards and references for vegetated concrete.Besides,the research trends in vegetated concrete technology and the mix design of actual engineering projects were summarized.The relationship between design parameters and mechanical properties of vegetated concrete was discussed,followed by a range of recommendations for mixed design parameters.Results show that the design porosity should be selected between 0.21 and 0.30,with an optimal range of 0.25 to 0.28,while the water-cement ratio should be chosen between 0.275 and 0.32.The average aggregate particle size selection range is relatively broad,ranging from 8 to 30 mm,with an optimal size between 13.5 and 23 mm.
