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-

Yoshinogari墓地(公元前50年左右)是日本最古老的填土建筑，是一种密实的分层土壤结构，使用了不同的土壤。寻找古代填筑技术的根源是以前的研究《日本古代填筑技术的根源及其变迁~从独屯墓葬到吉辛那加墓葬~(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。被认为是吉诺加里墓丘的直接根的杜氏墓的根是什么，以及填筑技术？根在哪里？对长江沿岸的许多填土(压实土结构)进行了岩土工程调查，其中包括良渚文化时代(公元前3300~2200)的填土，以及黄河沿岸的荣山文化时代(公元前2500~2000年)的填土，如山东济南。作为这些结果，旧的…中国填筑较多的是湛江流域长头遗址，压实方法为太极库，压实松散，横断面上没有汉池库那样精确的水平等深层。可以说，在这一地区，太极库一直沿用到大规模杜屯墓的修建。另一方面，在黄河地区，细粒黄壤S沉积的仰绍文化时代的西山充填(公元前330年~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韩赤古构造。两河流域填筑施工技术的传播和交流尚不清楚，近年来，在上通沿海地区发现了一些杜屯墓。吉诺加里遗址、江南杜屯墓和上通杜屯墓的直接根源是什么？尚需进一步研究，包括对上通杜屯墓的岩土工程勘察，才能弄清这一课题。较少

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
