Survey and Preliminary Analysis of a Third-Century Brick-Chambered Tomb with Squinch Vaults in China
摘要
This survey report emphasizes a third-century CE Chinese brick-chambered tomb with squinch vaults. Based on digital survey and construction-foot analysis, this study reconstructs the tomb's original ideal plan and its combination of square and circular elements. The axes of the two ancillary spaces were offset from the main-chamber axes, possibly due to ritual purposes. Faced with irregularities in the plan and varying barrel vault heights, craftsmen fully exploited the squinch's flexibility to organically adapt to differing geometric constraints. This study posits that third-century Chinese craftsmen adapted a universal prototype to the tomb plan dictated by Chinese funerary rituals. These practices, in turn, expanded the existing genalogy of squinch vaults from the perspective of geography and construction techniques.
