| Research Abstract |
The Yoshinogari burial mound (Funkyuu tomb) is a firstly compacted soil structures using a Hanchiku (ancient fill-construction method) technique in nearly B.C.50. What is the root of the Yoshinogari burial mound and its ancient fill- construction technique? The authors focused on the Du-Tun (burial mound) tombs in the south area of Chanjiang Rivet in China, which were constructed in nearly B.C.1100 to B.C.400 and which were considered as the direct root of these mound and technique. We firstly conducted geotechnical field tests on some Du-Tun (burial mound) tombs and laboratory tests for the mound soils.
There are two kinds of Du-Tun (burial mound) tombs for nobility and common people. The tombs of nobility is greater in size and Hantiku technique is used in this construction. Some lands of soils were compacted in layer in order to have some needs function such as strength, drain, waterproofing and etc. Some similarities between the Du-Tun tombs and the Yoshinogari burial mound are found from these investigations.
It is considered that before the establishment of Rakurogun (Japanese name, B.C.108) in Korea , there is no burial mound such as the Du-Tun tombs in this area. And it is said that in South Korea any burial mounds older than the Yoshinogari burial mound haven't been discovered yet.
From above investigations and considerations, it can say that the Du-Tun tombs' construction technique, namely the ancient Hanchiku, technique propagated from China through the sea to North Kyusyu, not through the Korean Peninsula.
