| Abstract: | The railway tunnel lining in cold area is prone to freezing damage in winter.In this paper,the present situation of freezing damage and its causes are analyzed.The measures of installing Electro-thermal def lector to prevent the freezing damage of railway tunnel lining is proposed and also applied in a tunnel.The results show that the installation of Electro-thermal def lector may effectively prevent the leakage of the lining,thereby avoiding the occurrence of freezing damage of the railway tunnel lining.The remediation effect is good,which can provide a remediation method for similar freezing damage treatment project of the railway tunnel lining in cold area. |
