So it isessentialto developthe so-calledactivemethod, that is more efficiently, environmental friendly and energy-efficient, to cope with tunnel freezing damages. This paper introduces the research of the principle and usage of heat pipe with ground source heat pump system using natural resources to heat tunnel lining and its applications. And it is suggested that the transportation engineering manage departments should pay much atten
