吉珲客运专线路基冻胀变形及影响因素分析

随着我国在严寒地区高速铁路的发展,路基冻胀变形对高速铁路的影响凸显出来,针对路基冻胀变形规律及影响因素的研究尚不完善,根据吉珲客运专线路基冻胀变形监测数据,采用综合分析方法分析了本线路基冻胀变形的一些规律,并对冻胀变形影响因素进行分析。通过分析得出吉珲客运专线路基冻胀变形规律及基床表层变形所占比例的不同与产生原因的对应关系。

Analysis of Frost Heave Deformation of the Subgrade on Jilin-Hunchun Dedicated Passenger Railway Line

With rapid development of high speed railway in cold area,the effect of subgrade frost heaving deformation is becoming more prominent. In view of the insufficient researches on the patterns of subgrade frost heaving deformation and the influencing factors,and with respect to Jilin- Hunchun passenger dedicated railway for subgrade frost heave deformation monitoring data,this paper analyzes comprehensively the laws and influencing factors related to the subgrade frost heaving deformation of this railway line. The results demonstrate the laws in question and the correlation between the percentage of the bed surface deformation and the causes of deformation.
