Abstract
Flood control initiated Chinese civilization. Chinese civilization has a long history, and Chinese ancestors invented “aquatic engineering technology” for flood control and water management, including the Fascine body, as early as two thousand years ago. The Fascine body is a structure used to protect the bank and prevent breaching of an ancient Chinese flood control project. Excavation of the Shahe ancient bridge ruins in Xi’an City, Shaanxi Province, China led to discovery of a Fascine body structure. Through 14C dating, fibre, slice observations, infrared spectroscopy, X-ray diffraction, thermogravimetric analyses and SEM energy spectrum analyses of the fascine material, microbes in the structure and the surrounding soil were identified, the dominant microbial community was analyzed, and microbial diseases were controlled in a targeted manner. Research on the fascine bank ruins identified the width and length boundaries of the Shahe ancient bridge, determined the exact age of the Shahe ancient bridge, provided important materials for research on ancient bridges, river embankments and other ruins, and provided important clues for the traffic and layout around Chang’an during the Qin and Han Dynasties of Chinese history.
Highlights
The Shahe ancient bridge ruins are located in the Shahe River Channel, Qindu District, Xi’an City, Shaanxi Province, China
We identified and analysed the fascine materials found in the Shahe ancient bridge ruins in Xi’an, Shaanxi, and determined the differences between dominant microbial species and bridge pier microbial species to find an antifungal reinforcing agent for the fascine materials in a targeted manner, and provides a certain scientific basis for long-term preservation of the Shahe ancient bridge ruins (Fig. 1)
The silt layer is called a “Fascine bank”, that is, a bank built with a fascine body
Summary
The Shahe ancient bridge ruins are located in the Shahe River Channel, Qindu District, Xi’an City, Shaanxi Province, China. In 1989, the Shahe ancient bridge Ruins were named one of China’s “Top Ten New Archaeological Discoveries”. The layout of the Shahe ancient bridge Ruins is clear, and the preservation of wooden structure bridge piles is complete. The piles are the largest and oldest large-scale wooden structure bridge piles in the world. Research on piles provides important physical materials regarding the history of bridge construction, the history of bridge development, and the history of ancient.

Tree rings and cave animal analyses can aid in identifying river and lake traces [2,3,4]
