Abstract

A composite embankment structure includes an embankment, an airflow-enhanced embankment ventilation structure, and a heat pipe system. The embankment includes an embankment filler layer, a ventilation slab lower leveling layer, a ventilation slab upper cushion, and a pavement structure layer arranged in sequence from bottom to top. The ventilation slab in the airflow-enhanced embankment ventilation structure is arranged between the ventilation slab lower leveling layer and the ventilation slab upper cushion. The heat pipe system includes a heat pipe, and one end of the heat pipe is inserted into the embankment from an embankment slope and is located under the ventilation slab.
