青藏铁路多年冻土区工程地质勘察技术研究

Research on the Technology of Engineering Geology Investigation about Permafrost along Qinghai-Tibet Railway

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： In permafrost region along Qinghai -Tibet railway, the natural environment is extreme, and the engineering geology condition is complex, and the ecological environment is vulnerable. It is more difficult to investigate in this region than anyplace else. The engineering geology investigation in permafrost region is a scientific research and exploratory investigation. It is important to research and sum up about technology of engineering geology investigation. Research conclusions： To engineering geology investigation, we consider not only the special engineering geology condition, but also environmental protection and natural environment influence, especially, the extreme climate influence. These were very striated with the engineering geology investigation about permafrost along Qinghai -Tibet railway. Through summing up engineering geology investigation, a complete set of investigation technology was formed, which was reliable to construction, and suited the Qinghai -Tibet railway. Including： constituted the criterion, organization mode, management, means and measures, supervisal, environment protection, and so on. To research and sum up about technology of engineering geology investigation, which can be referenced to the Qinghai - Tibet altiplano and other regions.
