| 摘 要： | 为探求基于主动冷却思路维护青藏铁路冻土路基稳定并适应青藏铁路建设和运营数字化的要求,进行了采控冷量维护冻土路基数值仿真系统的开发。系统集成了多种不同的采控冷量布管方式如水平纵向管路、倾斜管路、超低温制冷等,每种方式又分别考虑了不同水平的制冷参数,提供了自路基施工完成后20年内的路基和地层温度场演变以及不同采控方式之间的相互比较,界面友好,结果表现直观,方便了决策参考。

| Abstract: | Based on the thoughts of active cooling to keep the QinghaiTibetan Railway embankment stabilization and the digital need of the QinghaiTibetan Railway construction and management,the numerical simulation system of gathering cold energy to keep frozen soil roadbed's stabilization was developed.The system has integrated different methods to gather cold energy such as horizontal pipes and tilt pipes.According to each method different parameters are used.The system gives the temperature fields of the roadbed and the ground below after the finishing of the roadbed.The interface is friendly and the results are intuitionistic. |
