摘要
孙家城是目前长江下游发现的仅有的2座史前城垣之一,筑于距今4500年前后。本文尝试复原了筑垣的技术过程,认为其采用了斜坡堆筑法,在基础及土料处理、坡度设计等方面具有明显的设计和规划,心墙的混合土料与小层交错堆筑方法应是一种业已规范的技术。通过对垣、壕的特点分析并结合现实地形、降水数据,推测兼具防洪及防御功能,但垣的防御功能有限。
Dating to about 4500 BP,the Sunjiacheng site is one of the two prehistoric walled towns that have been found so far in the lower Yangtze river valley.This article reconstructs the constructional process of the encompassing wall.The author proposes that the constructional technique belonged to the so-called‘slope-stacking’technology.The reconstruction of this technique indicated that the construction of the foundation,the preparation of stacking earth,and the slope were clearly well-planned.In addition,the mixed earth filling for the center part of the wall and the stacking up of interlacing layers also represented that the construction method was highly standardized.In juxtaposing with the characteristics of the wall and moat and the analysis of topography and precipitation data,the author suggests that the wall should serve for both flood protection and fortification.However one should not overestimate the function of the wall for the later purpose.
