摘要
青藏高原气候暖湿化现象的持续,对青藏铁路安全平稳运行提出了更高的要求.在气候环境变化条件下,西大滩盆地与安多盆地之间的多年冻土退化所引发的基础设施变形是青藏铁路面临的最大挑战.青藏铁路建设初期,就从调控对流方式、调控传导方式及调控辐射方式三个角度研究了青藏铁路多年冻土的保护措施.本文介绍了目前针对多年冻土问题所采取的各类维护措施,将不同技术的特点和优势进行综述,并得出结论:未来针对青藏铁路多年冻土的保护措施应结合现有技术的成功经验,发挥新材料和新能源的优势.
Abstract
The continuous warming and humidification of the climate on the Qinghai-Tibet plateau has put forward higher requirements for the safe and stable operation of the Qinghai-Tibet railway.Under the conditions of climate and environmental change,the deformation of infrastructure caused by the degradation of permafrost between the Xidatan Basin and the Anduo Basin was the biggest challenge faced by the Qinghai-Tibet railway.Since the early stage of the construction of the Qinghai-Tibet railway,protective measures for permafrost on the railway have been studied from three perspectives:regulating convection mode,regulating conduction mode,and regulating radiation mode.This article introduced various maintenance measures currently taken to address the problem of permafrost,and summarized the characteristics and advantages of different technologies.The conclusion indicates that future protection measures for permafrost on the Qinghai-Tibet railway should combine the successful experience of existing technologies and leverage the advantages of new materials and energy.
