| Research Abstract |
The Yoshinogari burial mound (Funkyu tomb, around B.C.50), the oldest fill soil construction in Japan, is a densely compacted layered soil structure using different soils. Seeking the root of ancient fill-construction technique was the previous research "Root of ancient fill-construction technique in Japan and its change〜 From Du-tun (burial mound) tomb to the Yoshinogari burial mound〜 (Scientific Research(B), 2000〜2002)".
This research (Scientific Research(B), 2003〜2005) focused on the big subject as follows. What is the root of Du-tn tomb which is considered to be the direct root of the Yoshinogari burial mound, and Hanchiku (fill-construction) technique? Where is the root?
Geotechnical investigations have been carried out on many fills (compacted soil structures) along the Chanjiang River which include fills in Liangzhu culture era (B.C.3300〜2200) and along the Yellow River which include fills in Rongshan culture era (B.C.2500〜2000) such as in Jinan, Shanton.
As these results, the olde

st fill in China is the Changtou ruins in Chanjiang River basin and the compaction method is Taichiku, which is loosely compacted, and the cross section doesn't show exactly horizontal and constant depth layers such as Hanchiku. It can say that in this area, the Taichiku has been used until the construction of big scale Du-tun tomb.
On the other hand, in the area of Yellow River, where fine grained yellow soil s deposit, Xishan fill (B.C.3300〜2800) in Yangshao culture era is the oldest in this area. In or after the Rongshan culture era (B.C.2500〜2000), the Hanchiku structures which has exactly horizontal and constant depth layers can be found. The propagation and exchange of the fill construction technique between two rivers basins couldn't be made clear.
In recent years, some numbers of Du-tun tomb were found is in the coast are of Shangtong province. Which is the direct root of the Yoshinogari ruins, the Du-tun tomb in the south area of Changjiang River or in Shangtong? It needs more research including Geotechnical investigation on the Du-tun tomb in Shangtong in order to make clear the subject. Less
