路基稳定性是青藏铁路冻土路基工程面临的主要技术难题之一。结合青藏铁路安多段冻土路基的设计资料,分析沼泽化斜坡湿地冻土路基稳定性的影响因素和采取的技术措施,在此基础上对安多段沼泽化斜坡湿地冻土路基的稳定性和温度场进行长期监测,研究路基长期稳定性和安全性,同时分析路基体温度场变化对路基稳定性的影响和技术措施的合理性,提出沼泽化斜坡湿地冻土路基合理结构,为类似工程的设计和施工提供了参考依据。
Subgrade stability is one of the main technical problems faced by the Qinghai-Tibet Railway permafrost subgrade. Based on the design data of the Embankment of Antu Section of Qinghai-Tibet Railway, the influencing factors and technical measures for the stability of wetland subgrade in swampy slope are analyzed. On the basis of this, the stability and temperature Field long-term monitoring to study the long-term stability and safety of roadbed, and analysis of roadbed temperature field changes on the stability of subgrade and technical rationality of the proposed wetland swamp slope wetland roadbed reasonable structure for the design of similar projects And construction provides a reference.
