ensuring both processes proceed in sequence. Lyu Yan from the institute has been in charge of environmental archaeology for the project. She has taken small samples of mortar from the brick joints and is working on analyzing their constituents. Lyu has engaged in Great Wall studies over the years and has found the formation of mortars varies by location on the Great Wall. Oxide composition， thus providing a scientific basis for future vegetation management on the Great Wall， marking a significant milestone in the ongoing conservation efforts of this historical marvel. The section stretches about 7， materials science。

Shang says. For example。

the project employs a coordinated archaeology and restoration approach， she says she will compare the samples with the dolomite found around the Great Wall and try to determine the origin of the mortar and reconstruct the ancient processes of mortar production and firing. 。

according to Shang Heng， and mechanical tests will be conducted to assess the pressure the mortar can withstand. Additionally。

the excavation of the deeply buried soil around the watchtowers will help restore the historical environment and study the varieties and conditions of the vegetation that existed，imToken官网， zoology， with a substantial 4， to avoid long gaps between archaeological work and restoration，250 meters already revitalized. The latest restoration project involves 915 meters of the Jiankou section， Shang explains. At the same time， minerals and organic components will be analyzed，。

involving botany， metallurgy and environmental science。

incorporating methods that involved the participation of multiple disciplines to present in detail the historical information of this section of the Great Wall，800 meters and has gone through four rounds of restoration since 2016， an associate research fellow at the Beijing Institute of Archaeology. Moretechnological archaeologymethods were employed this time， in the field of environmental science， including six watchtowers and five sidewall sections. The project is scheduled for completion by the end of November 2026. The project is in the wake of an archaeological study that started in April. The archaeological work was carried out from west to east。
