研究目的:青藏铁路多年冻土区的自然环境恶劣,工程地质条件极其复杂,生态环境脆弱。多年冻土区工程地质勘察比其他任何地区的勘察工作都更有难度,对于勘察工作具有很强的研究性与探索性,因此有必要对青藏铁路工程地质勘察技术进行研究和总结。研究结论:青藏铁路多年冻土区工程地质勘察工作,不仅需要考虑独特的多年冻土地质条件,还要兼顾环保因素、自然因素等,特别是恶劣的自然因素对勘察工作的影响,这些对青藏铁路多年冻土工程地质勘察都提出了很高的要求。通过对青藏铁路的工程地质勘察工作的研究和总结,研究形成了适应于多年冻土区,而且经设计、施工、运营验证的可靠的全套工程地质综合勘察技术,包括:勘察标准的制定、勘察组织模式、勘察管理、勘察方法和手段、勘察监理、环保勘察等,为青藏高原以及其它冻土地区的勘察提供有益的借鉴和经验。
Research purposes: The permafrost region of Qinghai-Tibet Railway has poor natural environment, extremely complex engineering geological conditions and fragile ecological environment. Geological prospecting in permafrost regions is more difficult than any other survey work in the region, so it is of great research and exploratory work for prospecting work. Therefore, it is necessary to study and summarize the engineering geological survey techniques of the Qinghai-Tibet Railway. Research conclusions: The engineering geological prospecting in the permafrost region of the Qinghai-Tibet Railway not only needs to consider the unique geological conditions of permafrost, but also take into account the environmental factors, natural factors, especially the impact of poor natural factors on the investigation, Railway permafrost engineering geological survey have put forward very high requirements. Through the research and summary of the engineering geological survey of the Qinghai-Tibet Railway, the study has formed a reliable comprehensive engineering geological comprehensive survey technology that has been adapted to the permafrost region and has been verified through design, construction and operation, including the establishment of survey standards, Organization model, survey and management, survey methods and means, survey and supervision, environmental investigation, provide useful reference and experience for the investigation of Qinghai-Tibet Plateau and other frozen soil areas.
