摘　　要：在Lombardi博士的GIN理论基础上,结合世界大坝委员会的坝基设计公报及以往国际水电站工程采用GIN灌浆取得的经验,依托科特迪瓦波波里水电站土石坝帷幕灌浆的实践,阐述了基于坝基岩石质量与压水试验成果的GIN设计值的取值方法,提出了P_(max)、V_(max)值设计时需要考虑的两种边界条件,并通过理论公式计算及实践经验提出了浆液扩散半径的安全保证系数。On the basis of Dr.Lombardi's GIN theory,combined with the ICOLD bulletin concerning the foundation of dam and the GIN grouting experience of previous international hydropower projects,this paper relies on the curtain grouting practice of the earth-rock fill dam of the Gribo-Poboli Hydropower project in Cote d'Ivoire,and improves the GIN value design method based on the dam foundation rock quality and Lugeon water test results.Two extreme boundary conditions which should be considered in the design of P_(max)and V_(max)values are proposed,and the research process safety guarantee factor of slurry diffusion radius is proposed basing on theoretical formula calculation and practical experience.
