摘　　要：本文结合西藏地区某水电站土料勘察,对大口径钻孔在西藏地区特殊自然地理环境下土料勘察中的应用进行了分析研究,并就大口径钻孔勘探和常规勘探在西藏地区土料勘探中的应用进行了对比分析,总结了大口径钻孔在西藏地区土料勘察中的优势、不足及实用条件,为类似工程土料勘探提供了经验和借鉴。Combined with the earth materials investigation for a hydropower project in Tibet, the application of the large-diameter borehole to the earth materials investigation under the specific natural geographic environment of Tibet is analyzed and studied herein, and then a comparative analysis is made between the applications of both the the large-diameter borehole and the conven- tional drilling to the investigation of earth materials therein ; from which the advantages, defects and practicable conditions of the large-diameter borehole for the investigation of earth materials in Tibet are summarized, and then some experiences and references are provided for the earth materials investigation in the similar project concerned as well.
