冻土区接触网支柱基础位移影响研究

Study on Displacement of OCS Mast Foundation in Permafrost Region

本文提出了一种计算冻土区接触网支柱基础位移安全阈值的方法,通过选取具体的一种接触网支柱型号进行计算,得到Ф350钢管支柱基础的安全移动阈值,给出测量支柱倾斜数据的监测方案,对冻土地区接触网支柱基础的埋深设计及提高运营安全具有参考价值。

The paper presents a type of method for calculating the safety threshold values for foundation displacement of OCS mast in permafrost region,by selecting of a certain type of OCS mast for calculation,the safety threshold values of Ф350 steel pipe mast foundation and a monitoring scheme with finalized data of mast’s inclination are obtained,providing references for burying depth design and operational safety enhancement for OCS mast foundations in permafrost region.
