To evaluate the influence of site soil on damage caused by soluble salts, the “Acrobat figures” pit in the Emperor Qinshihuang’s Mausoleum were used as an example. The site environment, including temperature and humidity and the water content, salt types, soil components were surveyed.To do the research, density and clay content were selected as two important properties of soil. Simulation studies using blocks of soils having various densities and clay contents were designed. The blocks were subjected to specific temperature and humidity cycling conditions to investigate how these two factors affect the damage caused by the salt. It is found that when soil density and clay content change, the damage caused by the changes accordingly. The results with the damage caused salt at the “Acrobat figures” site were compared and the damage degree and risks were evaluated.
