中文摘要:川藏铁路是是具有重要战略意义的国家重点工程,同时也是铁路工程史上最具挑战性的工程。川藏铁路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,川藏铁路勘查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查孔进行的孔内试验项目和质量控制方案。通过精心的设计和施工,DZ-S-04-1号钻孔已顺利完工,为后续的工程建设提供了宝贵的数据和坚实的基础。

In hole test and quality control scheme of Sichuan Tibet Railway exploration project -- Taking DZ-S-04-1 borehole as an example
Abstract:Sichuan Tibet railway is a national key project with important strategic significance, and also the most challenging project in the history of railway engineering. The geological conditions along the Sichuan Tibet 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 in Sichuan Tibet Railway exploration project, including in-situ stress test, hydrological test, ground temperature test and comprehensive logging. Taking dz-s-04-1 borehole as an example, this paper introduces in detail the in hole test items and quality control scheme of the exploration hole in Sichuan Tibet railway. Through careful design and construction, dz-s-04-1 borehole has been successfully completed, which provides valuable data and solid foundation for subsequent engineering construction.
