基于海绵城市理念的透水铺装系统抗冻融破坏性能改良试验

摘要

海绵城市理念作为解决城市水环境问题的重要方案，强调水的自然循环与合理利用。透水铺装系统作为其核心组成部分，在城市建设中得到了广泛应用。针对透水铺装系统在寒冷地区面临的冻融破坏问题，本文通过实验研究，对透水铺装材料的抗冻融性能进行改良，以提高其在极端气候条件下的耐用性和稳定性。试验通过改良材料配比和增强技术，发现适当的改良措施能够有效提高透水铺装的抗冻融破坏能力，从而延长其使用寿命，优化海绵城市的建设效果。研究结果为透水铺装在寒冷地区的应用提供了理论依据与实践指导。

Abstract

As a crucial solution to urban water environment issues, the sponge city concept emphasizes the natural circulation and rational utilization of water. As a core component of this concept, permeable pavement systems have been widely applied in urban construction. Aiming at the frost-thaw damage problem faced by permeable pavement systems in cold regions, this paper conducts experimental research to improve the frost-thaw resistance of permeable pavement materials, so as to enhance their durability and stability under extreme climatic conditions. Through modifying material proportions and enhancing technologies, the experiment finds that appropriate improvement measures can effectively enhance the frost-thaw damage resistance of permeable pavements, thereby prolonging their service life and optimizing the construction effects of sponge cities. The research results provide a theoretical basis and practical guidance for the application of permeable pavements in cold regions.
