中国古代早期建筑基址柱与地面连接方式的演变及受力特征分析

Analysis on Mechanical Performance of the Connections between Column and Base in Early Ancient Chinese Architecture and Its Evolution

深入整理中国早期建筑考古资料,梳理并分析早期建筑柱与地面连接方式的演变过程,并定性分析其受力特点,对比发现柱与地面连接方式有一个形状由尖到平,材料由简单到复杂,埋深由深到浅的过程,其受力性能也趋向于合理。进而认为,随着这一结构环节的变化,柱与地面连接方式趋于成熟稳定,而柱与上部梁架连接方式逐渐成为后来建筑结构发展的主题。这一发现能够为中国木结构发展缘起提供一个更为深入的分析环节。

By in-depth sorting of the archeological material of early Chinese architecture and qualitative analyzing its loading features at the connections between column and the base and its evolution,the author found the connections had undergone a process from sharp to flat in shape,from singularity to diversity in material,from deep to shallow in depth,and a tendency of reasonable in mechanical performance.And it is believed that this change reflects maturity of the design and understanding which forms the basis for the connections at other locations such as column and the beam which later became the major focus of design.This study may provide a step stone more towards deeper qualitative analysis on the origin of Chinese timberwork.
