摘　　要：为推进我国绿化混凝土的研究进展与推广,采用归纳总结的方法,对绿化混凝土现阶段的研究状况进行了总结概括,并针对绿化混凝土的四大主要问题——孔隙率、孔隙盐碱环境、强度、种植问题进行了深入了解和探讨。通过研究,确定了最低孔隙率及孔隙率的种类、中和处理孔隙盐碱环境的方法,强度的影响因素以及草种、种植方式选择。并结合工程实例,分析了绿化混凝土的不足。提出优化绿化混凝土结构形式,建立混凝土—根力学模型,通过数值模拟,以加快绿化混凝土的研究。To promote the research progress and popularization of green concrete, using the methods of induction and generalizations, the current situation of greening concrete were studied and summarized, the four main problems, green concrete, the porosity, the environ- ment, the strength and the planting of the green concrete, were deeply understood and discussed. Through the research, the method of the lowest porosity, the type of porosity, and the method of treating the saline alkali environment, strength influence factors and grass plant- ing mode choice were determined. Combined with the engineering example, the deficiency of the green concrete was analyzed. Optimiza- tion of green concrete structure form, concrete-root mechanics model was set up by numerical simulation, to speed up the research of green concrete.
