摘　　要：糯扎渡水电站坝基花岗岩风化复杂，尤其是右岸的构造软弱岩带附近，对坝基的工程地质条件影响极大，为枢纽区主要工程地质问题之一。本文从风化花岗岩物质特性和风化岩体的分布入手，总结其物理、力学性成果，说明工程地质特性，为坝基处理提供参考。The dam foundation granite weathering of Nuozhadu Hydropower Station is complex, especially the nearby of the right-bank weakened rock zone exerts huge effect on the engineering geological conditions of the dam foundation, which is one of the major engineering geological problems. This paper starts with the material characteristic and distribution of the weathered grantie mass, then summarizes the physical and mechanical results, and explains the engineering geological characteristic, so as to offer reference for the dam foundation treatment.
