摘要
气候变暖的背景下,青藏铁路冻土路基稳定性面临严峻挑战,主要表现为路基出现沉降、开裂等病害。本文通过分析青藏铁路多年冻土区K1496+750路基断面地质条件,对本断面路基沉降产生原因进行分析,并通过分析长周期的变形监测数据,讨论了路基采取块石护坡和热棒等防护措施的作用效果,为多年冻土区路基病害防治提供借鉴。
Under the background of climate warming,the Qinghai-Tibet Railway embankment stability is facing serious challenges in permafrost regions,mainly for embankment settlement,cracking and other diseases.In this paper,by analysis the embankment section K1496+750 of Qinghai-Tibet Railway geological conditions,causes of embankment settlement at this location are investigated.And by studying the long-term deformation monitoring data,the effects of protective measures such as crushed rock revetment and thermosyphons were discussed,so as to provide reference for the prevention and treatment of roadbed diseases in the future permafrost area.
