| Earthen site is the ancient site of soil as the main material, it is one of the important historical carriers of human life, production, religious and military activities. As a result of water and salt transport in the soil of the crisp base, flake off, root cutting, and other diseases in the soil remains widespread, but also a problem to be solved. Although there have been many studies on the salt damage of rock and soil types, most of them are about the salt content, salt type, salt crystallization or environment. Less from the soil itself, researching the impact factors of salt damage. This study takes the Baixi figurines pit as the object to investigate the relationship between the effect of the properties of soil, the ruins of soil salinity. Baixi figurines pit is located in between the walls inside and outside the mausoleum of the first Qin emperor seal southeast of soil, underground tunnel type of civil engineering and architecture, because of its discovery in 1999, and therefore it is also called for K9901 pits. First investigating Baixi figurines pit building shapes, occurrence environment and noumenon, including temperature and humidity, moisture rate, salt types and salt content, disease, soil etc. Second, according to the survey results to make simulation of different density and different content of clay block temperature and humidity cycling test, and discuss the influence of these two factors on the ruins of the salt damage. Density and clay content is affects the soil texture of the two macro factors, and is easy to be simulated, so the choice of these two factors to test first. The experiment showed that the salt damage law and Baixi figurines pit soil control, and ultimately determine whether the Baixi figurines of salt damage and salt injury risk. This study is to enrich the theoretical research system of earthen sites, which is helpful to the treatment of the disease, and also can help to evaluate the risk of salt damage... |
