钓鱼城加担土遗址夯土结构成分与回弹强度的纵深变化规律研究
Research on Characteristics of Rammed Earth Structure Composition and Rebound Strength with Depth at Jiadan Earthen Site in Fishing Town
摘要
Abstract
The unique rammed earth structure of the Jiadan Earthen Site in Fishing Town,Hechuan,Chongqing,has attracted widespread attention following systematic archaeological investigations and excavations of this site in recent years.However,in-depth research on the composition and structural strength characteristics of this site remains insufficient.Laboratory experiments and field exploration were employed to systematically explore the overall multi-layered structure of the rammed earth mass and analyze its composition and rebound strength.Field exploration results indicated that the overall rammed earth structure exhibited distinct characteristics of rammed earth wrapped around stones,which was divided into 16 soil layers from shallow to deep according to their characteristics.Mineral composition and micromorphological analysis showed that the rammed earth mass was mainly com-posed of quartz,albite,and illite.The weathering degree gradually decreased from the 1st to the 3rd layer,was relatively severe in the 4th layer,and then alternated between high and low in subsequent layers.Combined with the variation trend of rebound strength with depth,the weathering degree of the rammed earth mass of the Jiadan Earthen Site decreased with increasing depth.In heavily weath-ered layers,the rebound strength was positively correlated with quartz content,while in lightly weath-ered layers at depths greater than 100 cm,the rebound strength was negatively correlated with quartz content.This study provides a valuable reference for the research on the unique rammed earth technol-ogy of the Jiadan Earthen Site and enriches the existing knowledge of ancient rammed earth engineer-ing technology.关键词
