Abstract

This paper presents how to analyze heat transfer characteristics of double-layered soils. Thermal response tests were conducted to measure the ground thermal conductivities of Joomunjin sand and double layered soils filled in a steel box of which the size is $5m{\times}1m{\times}1m$. Double-layered soils were composed of Joomunjin sand and Kaoline clay. Each thermal conductivity of Joomunjin sand and Kaloine clay was measured by using Heat Flow Meter considering different void ratio. The ground thermal conductivity of double-layered soils was 15% smaller than that of Joomunjin sand.
