Cemented gravel dam construction technique combines the advantages of earth-rock dams and concrete dams, and has broad application prospects. Taking Shaping first-level Hydropower Station as an example, production tests were carried out on C1806, C18010 and C18020 cemented sand and gravel, and core drilling tests were carried out on their compressive strength, splitting tensile strength, permeability and SEM scanning tests at the age of 180 days. The results show that under scientific ratio and reasonable construction technology, the compressive strengths of C1806, C18010 and C18020 have reached 7.1 MPa, 14.8 MPa and 29.4 MPa, respectively. Among them, the impermeability grade of C18010 with the largest amount of project consumption is W8. The performance of cemented sand and gravel can achieve the expected results, which verifies the feasibility of the construction plan. Thus, it provides technical support for subsequent construction, and also provides reference examples for subsequent hydropower station construction.

胶结砂砾石筑坝技术融合了土石坝和混凝土坝的优点,具有广阔的应用前景。以沙坪一级水电站为例,对C1806、C18010、C18020胶结砂砾石进行了生产性试验,并在180 d龄期时钻芯对其进行了抗压强度、劈拉强度、抗渗度及SEM电镜扫描试验。结果表明,在科学配比和合理的施工工艺下,C1806、C18010、C18020抗压强度分别达到了7.1、14.8、29.4 MPa,其中工程用量最多的C18010抗渗等级为W8,胶结砂砾石的性能可达到预期效果,验证了施工方案的可行性,可为后续施工提供技术支持,也为后续水电站建设提供了可借鉴的范例。
