摘要
简要总结了自上世纪六七十年代以来青藏铁路多年冻土路基工程技术探索与实践过程,认为青藏铁路多年冻土路基设计应以冻土地基稳定为核心,依据冻土年平均地温、含冰量、不良冻土现象及水文地质等,考虑全球气温升高及其他因素的影响,以科学试验为指导,采取主动保护冻土的措施动态设计,为列车快速通过高原提供技术保证。
This paper summarizes the exploration and practice of permafrost subgrade engineering technology in Qinghai-Tibet railway since the 1960s. It believes that the design of permafrost subgrade of Qinghai-Tibet railway centers on the stability of the permafrost foundation and is based on the average temperature of permafrost, ice content, and poor permafrost phenomena and hydrogeological conditions. It takes into consideration the rise in the global temperature and other factors. It is guided by scientific experiments and takes the initiative to protect the permafrost. Its dynamic design provides technical guarantee when the trains pass through the plateau.
