The Transition of Rammed Earth Technology in Ancient China

In this paper, we looked at the rammed earth technology used in the earthen ramparts in ancient China. So far, research related to the rammed earth in China has focused on the combination of pangoe(版塊) and individual traces such as woodboards, wooden pillars, horizontal woods, and strings, and there has been a lack of attempts to identify the rammed earth technology of the entire rampart of each remains. I examined the rammed earth pattern of the entire rampart through the examination of the rampart earth structures and rampart methods. As a result, China's ancient rammed earth technology appears when ramparts begin to be built on mid~downstream of the Yellow river in the late neolithic yangshao culture(仰韶文 化). In the literature records, it can be seen that in addition to rampart earth structures (corresponding to types A and C) that fix the wooden plates with wooden pillar called ‘jeong(楨)’and ‘gan(幹)’, Chinese ancient ramparts were built using various rampart earth structures. The rammed earth method also used various methods such as banggoe rammed earth(方塊 版築), bundan rammed earth(分段版築), yeonjeop rammed earth(連接版築), and if you look at the relationship with the rammed earth structure, you can see that each rammed earth method uses one or two types of rammed earth structures to build the rampart. In particular, the appearance of methods for connection of wood plates and supporting and fixing the wood plate by using horizontal wood has led to a change in the rammed earth structure as well as its methods too. In the meantime, archaeological investigations of ramparts in China have been conducted mainly in the midland areas, and the study of construction technology was not very detailed, so it is still difficult to specifically identify the transformation of rammed earth technology in other areas except mid~downstream of the Yellow river. In the future, if archaeological research and research continue to be accumulated and a lot of achievements, we hope that more advanced research will be conducted not only on the transformation of rammed earth technology in each region of China, but also on its relationship with Korea, and I hope that this paper will help us understand Korea's ancient rammed earth technology.
