青藏公路多年冻土地区路基病害是制约青藏地区道路发展的一个重要问题。热棒是防止多年冻土路基上限下降的措施，为了研究热棒路基的降温效果，动态监测青藏高原五道梁地区百米路基试验路段的温度变化，通过与一般路基对比，分析了热棒路基在多年冻土地区的降温效应。研究发现：热棒路基能够有效地降低路基温度、保护冻土和增强路基热稳定性。

Subgrade failure of Qinghai-Tibet Highway in permafrost areas is an important issue that constrains highway development in Qinghai-Tibet region. Heat pipe is an effective measure to avoid settlement of the upper limit of permafrost subgrade. In order to research the cooling effect of heat pipe subgrade, the temperature of one-hundred-meter-long subgrade test section in Wudaoliang of monitored dynamically. Through comparison S S ubgrade in permafros with the common subgrade, the t areas was analyzed. It is founded that heat pipe ubgrade temperature, protect permafrost and stre Qinghai-Tibet Plateau was cooling effect of heat pipe subgrade can effectively reduce ngthen subgrade thermal stability.
