摘　　要：西藏雅鲁藏布江藏木水电站施工开挖期坝基岩体进行了物探检测,确定了松驰带,得出了岩体波速、岩体模量、岩体透水率等参数并对岩体固结灌浆效果进行了评价,为藏木水电工程设计提供了依据。In the dam foundation excavation period of Zangrnu hydropower station, which is located on the middle reaches of the Yarlung Zangbo River in Tibet, geophysical detection was carried out. The rock mass geophysical pa- rameters including sonic velocity, rock mass modulus （deformation modulus and elastic modulus） and water permea- bility rate were obtained and the effect of rock mass consolidation grouting was evaluated, which provides basis for de- sign of Zangmu Hydropower Station and gives a reference to design of other hydrooower stations of this kind in Tibet.
