摘　　要：拉西瓦水电站是黄河上游最大的水电站工程,右岸地下厂房系统具有深埋性、洞群式、大跨度、高边墙、延伸长等特点。随施工进展,地质编录、图件绘制、超前预报、计算分析等施工地质工作同步进行。简要总结主、副厂房洞室围岩的分类,并将其与前期勘探资料进行了对比,两者围岩类别划分基本一致。Laxiwa hydropower station is the largest one on the upstream of Yellow River. The underground powerhouse on the right bank is characterized with deep embedment, tunnel group, long - span, high - wall, long - extension, etc.. With construction progress, geologic log, mapping, geological forecasting, computation and analysis, a brief summary is presented for surrounding rock classification of the powerhouse and service building, and the classification results are basically in accordance with pregeological data.
