A Study on the Relationship between Roadbed Thickness With Insulation and Earth Temperature of Qinghai-Tibet Railway

Liu Caiyun;Guo Zunguang;Department of Science,Taiyuan Institute of Technology;  
Through the construction of uniform dielectric hierarchy pure heat conduction model of roadbed with insulation in Fenghuo Mountain section of Qinghai-Tibet Railway,combined with the temperature function of permafrost surfaceobtained by hierarchy approximate solution and the theoretical temperature expression of permafrost given by Lunardini,the implicit equation among the packing layer,insulating layer,the annual average surface temperature of roadbed and amplituderelations of sinusoidal variation temperature isobtained.Finally,an analysis of the re-lationship among these three elements is carried out with this equation.
