Analysis and appraisal of fascine in Shahe ancient bridge ruins, Xi’an, Shaanxi, China

Abstract Flood control initiated Chinese civilization. civilization has a long history, and ancestors invented “aquatic engineering technology” for flood water management, including the Fascine body, as early two thousand years ago. The body is structure used to protect bank prevent breaching of an ancient project. Excavation Shahe bridge ruins in Xi’an City, Shaanxi Province, China led discovery structure. Through 14 C dating, fibre, slice observations, infrared spectroscopy, X-ray diffraction, thermogravimetric analyses SEM energy spectrum fascine material, microbes surrounding soil were identified, dominant microbial community was analyzed, diseases controlled targeted manner. Research on identified width length boundaries bridge, determined exact age provided important materials research bridges, river embankments other ruins, clues traffic layout around Chang’an during Qin Han Dynasties history.
