摘 要: 胶凝砂砾石是一种介于混凝土与堆石料之间的新型筑坝胶凝材料,具有节约资源、降低造价、保护环境等优点，对胶凝砂砾石材料的特性研究是坝体结构设计的关键，目前对于胶凝砂砾石材料的特性研究缺少较为全面的认识。为使胶凝砂砾石材料更好的应用于实际工程，因此通过文献查阅，本文总结了胶凝砂砾石材料的力学性能和冻融环境下的材料耐久性等方面试验研究，对胶凝砂砾石材料特性受胶材用量、单位用水量、水胶比、砂率、龄期等多种参数的影响规律进行综合分析，为胶凝砂砾石筑坝材料的进一步研究和应用提供理论基础。

Abstract: Cementitious sand and gravel is a new type of dam cementing material between concrete and rockfill. It has the advantages of saving resources, reducing cost and protecting environment. The study of the characteristics of  cementitious sand and gravel materials is the key to the design of dam structure. At present, there is a lack of comprehensive understanding of the characteristics of  cementitious sand and gravel materials. In order to make the cementitious sand and gravel material better applied to practical engineering, through literature review, this paper summarizes the mechanical properties of cementitious sand and gravel materials and the durability of materials under freeze-thaw environment are summarized, and the characteristics of cementitious sand and gravel materials are comprehensively analyzed by the influence of various parameters such as rubber dosage, unit water consumption, water-glue ratio, sand rate, age, etc.,so as to provide a theoretical basis for further research and application of cementitious sand and gravel damming materials.
