摘要
冻土区铁路地基的冻胀和融沉将是威胁川藏铁路安全运营的不利因素之一,本文结合某铁路冻土区沿线设立的地温监测点,提出了基于地温监测数据实现对冻土地基冻融变化的可视化分析思路和方法。利用本文提出的可视化分析方法,可以直观、实时地展现冻土地基的冻融变化过程及其发生的时间和深度范围,为更好地研究川藏铁路冻土地基冻融特性及其发生的规律将提供直接帮助。
Frost heave and thaw settlement of railway foundation in permafrost area will be one of the negative factors threatening Sichuan-Tibet Railway safety operations.Combined with the ground temperature monitoring points established along one railway line in permafrost zone,this paper proposed the ideas and methods of visualization analysis of foundation freezingthawing changes in permafrost area based the geothermal monitoring data.Use visual analysis of the proposed method can be intuitive,real-time to show the time and depth scope of the freeze-thaw process changes and occurrence of permafrost foundation,and that will provide direct help to research freeze-thaw characteristics and occurrence regularity in permafrost foundation along Sichuan-Tibet Railway.
