强度与透水性是透水混凝土在工程应用过程中最受关注的两个核心问题，研究表明上述两者性能是相互矛盾的对立关系。本项目以强度和透水性的共同决定因素孔结构特征为切入点，首先，研究透水混凝土孔结构特征的要素及其表征方法。其次，试验研究透水混凝土的强度与透水系数，并分别建立孔结构特征与强度和透水系数的理论模型并揭示其作用机理。然后，以孔结构特征为桥梁，理论研究透水混凝土强度和透水系数之间不断变动的此消彼长的均衡关系，建立强度与透水系数的理论模型，探求适用于不同强度和透水性要求的透水混凝土性能的双目标优化方法，提出基于强度和透水系数的透水混凝土性能双目标优化模型及机理。本项目的研究对开发适应不同强度和透水性需求的透水混凝土材料具有重要价值，而且也可为相关标准的制定提供技术基础和可靠的设计参数，对其工程实践具有重要的指导作用。

Strength and permeability are two core problems of pervious concrete in engineering application, The research results show that the strength and permeability of pervious concrete is contradictory.This research is based on the pore structure features which is the common factor of strength and permeability. Firstly, the pore structure features of pervious concrete will be well studied.Secondly, the strength and permeability coefficient of pervious concrete will be studied. The theoretical models of pore structure features related to strength and also the relationship between the pore structure features and permeability coefficient will be established, and the mechanism of which will be revealed. Then, as the bridge of the pore structure features, the theoretical research of the equilibrium relationship between strength and permeability coefficient of pervious concrete will be carried out. The theoretical model of strength and permeability coefficient will be established. A double objective control method will be applied to the performance of pervious concrete with different strength and permeability. Based on the strength and permeability coefficient, the double objective control model and mechanism of pervious concrete are proposed. The research of this project is of great value to the development of pervious concrete materials to meet the needs of different strength and permeability. It can also provide technical basis and reliable design parameters for the establishment of relevant standards. It plays an important role in the engineering practice.
