Propagation route of Hanchiku (fill-construction method) technique in ancient China to Japan and its development -From the soil foundation in Liangzhu culture era, China to the ancient tomb in Japan-

日本最古老的填土建筑吉野场冢（Funkyu墓，约公元前50年）是用不同的土壤密集压实的层状土结构。寻找古代填筑技术的根源是前人的研究《日本古代填筑技术的根源及其变迁——从杜屯墓到吉野村墓（科学研究(B), 2000 ~ 2002）》。本研究（科学研究(B), 2003 ~ 2005）主要围绕以下几个大课题展开。被认为是吉野村墓地的直接根源的都津墓和填筑技术的根源是什么？根在哪里？对包括良渚文化时期（公元前3300 ~ 2200年）在内的湛江沿岸和山东济南等黄河沿岸包括荣山文化时期（公元前2500 ~ 2000年）在内的许多填充物（压实土结构）进行了岩土工程勘察。研究结果表明，中国最古老的填充物为Chanjiang流域的changou遗址，压实方式为Taichiku，压实方式较为松散，且断面不完全显示Hanchiku等水平等深层。可以说，在这一地区，太古一直被使用，直到建造了大规模的斗屯墓。另一方面，在细粒黄土沉积的黄河地区，仰韶文化时代的西山堆（公元前3300 ~ 2800年）是该地区最古老的。在荣山文化时代（公元前2500 ~ 2000年）或之后，可以发现具有精确水平和恒定深度层的Hanchiku结构。两河流域填筑施工技术的传播与交流尚不清楚。近年来，在山东沿海地区发现了一批都屯墓。吉野村遗址的直系根源，是江南的都屯墓，还是商通的都屯墓？尚需进行更多的研究，包括对上通杜屯墓的岩土工程调查，以明确主题。少

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 … More 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
