摘　　要：川藏铁路是铁路工程史上最具挑战性的工程。沿途地质条件非常复杂,内外动力地质灾害极其发育。针对可能发生的岩爆、涌水和岩体放射性等工程危害,川藏铁路勘察工程需进行大量的孔内试验,包括地应力测试、水文试验、地温测试和综合测井等。本文以DZ-S-04-1号钻孔为例,详细介绍了川藏铁路勘察孔进行的孔内试验项目和钻孔质量控制方案。通过精心的设计和施工,DZ-S-04-1号钻孔已顺利完工,各项孔内试验圆满完成,为后续的工程建设提供了宝贵的数据基础。Sichuan-Tibet Railway is a most challenging project in the history of railway construction.The geological conditions along the railway are complex,and the internal and external dynamic geological disasters are extremely developed.In view of the possible engineering hazards such as rock burst,water gushing,and rock radioactivity,a large number of in‑hole tests should be carried out for the Sichuan Tibet Railway investigation project,including in‑situ stress test,hydrological test,ground temperature test,comprehensive logging.Taking Borehole DZ-S-04-1 as an example,this paper introduces in detail the in‑hole test items and borehole quality control plan for the investigation hole for Sichuan-Tibet Railway.With careful design and construction,Borehole DZ-S-04-1 has been successfully completed together with the in‑hole tests,which provides valuable data basis for subsequent construction.
