在全球建筑业面临严峻环境挑战的背景下，浇筑土作为一种新兴的生土建筑技术，凭借其低碳环保特性与施工效率优势，在可持续建造领域，特别是乡村地区展现出巨大的应用潜力。本研究首先通过与其他同类材料的对比分析，阐明浇筑土的独特性与低碳优势；继而结合文献分析与材料实验，梳理提升浇筑土性能的方法与策略；最终依托实际浇筑土示范项目，从材料配比设计、装配式建造工法、施工流程以及隐含碳排放计算四个维度，构建低碳建造的技术范式并完成实践验证。本研究旨在为浇筑土技术在中国的发展与应用提供理论依据及实证案例，探索一条兼具生态效益与实施可行性的乡村可持续建造新路径。
Abstract：Under the global construction industry's severe environmental challenges,poured earth,as an emerging raw earth construction technology,demonstrates significant potential in sustainable construction due to its low-carbon environmental footprint and construction efficiency advantages. This study first employs comparative analysis to clarify the distinctive characteristics and advantages of over poured earth other earthen construction techniques. Subsequently,through a literature review,it systematically presents strategies for enhancing poured earth performance. Finally,based on demonstration projects,it establishes a technical framework and practical validation from four dimensions:material formulation design,prefabricated construction methods,construction processes,and embodied carbon emission accounting. The study aims to provide theoretical foundations and empirical cases for poured earth technology applications in China,exploring an ecologically beneficial and operationally feasible new pathway for sustainable rural construction.
