【Abstract】 The ventilating embankment is the engineering means to protect frozen soil in cold regions. It is a key to analyze its working mechanism and heat exchanged with environment to apply ventilating embankment. Based on principle to protect frozen soil and application effect of ventilating pipe in practical engineering, the heat changed mechanism between ventilating pipe and environment is analyzed. The noted principles are proposed when the ventilating embankment is analyzed and applied.更多还原
