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-

吉野狩墓（Funkyu墓，大约公元前50年）是日本最古老的填土建筑，是一种使用不同土壤的致密分层土壤结构。探寻古代填筑技术的根源是前期研究“日本古代填筑技术的根源及其变迁--从都屯墓到吉之冢墓（科学研究（B），2000 ~ 2002）"，本研究（科学研究（B），2003 ~ 2005）主要围绕以下大课题展开。被认为是吉野狩墓的直接根源的杜冢的根源是什么？根在哪里？对长江沿着的良渚文化时期（公元前3300年至2200年）的填土（压实土结构）和黄河沿着的荣山文化时期（公元前2500年至2000年）的填土（如济南、山东）进行了岩土工程勘察，结果表明，长江沿岸的旧填土（压实土结构）是一个典型的地质现象，但其地质特征和工程性质却与长江沿岸的地质特征有很大的关系 ...更多信息 我国最早的填土是长江流域的长头遗址，其压实方法为太赤窟，压实松散，横断面上没有像半赤窟那样精确的水平定深层。可以说，在这一地区，太极库一直使用到大规模杜屯墓的修建;另一方面，在黄河流域的细粒黄土存款沉积区，仰韶文化时期的西山填土（公元前3300年至2800年）是这一地区最古老的填土。容山文化时代（公元前2500 ~ 2000年）及以后，发现了水平等深的寒池库构造，两河流域充填建造技术的传播和交流尚不清楚，近年来，在商通沿海地区发现了多座杜屯墓。吉野狩遗址的直接根源是江南的杜屯墓还是上同的杜屯墓？尚待进一步研究，包括对商通杜屯墓的岩土工程勘察，以弄清这一问题。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
