| Chinese civilization has been through five thousand years, the ancestors passed away anymore, but a large number of ancient cultural heritage been preserved. Soil sites is an important part of ancient cultural heritage. Constituent materials of soil sites are mostly earthen sites adobe, rammed earth, resulting in soil sites face the constant erosion of weathering and soluble salts. Due to explosive growth of population, the attendant constant expansion of urban construction, the lack of scientific management and vandalism makes the habitat conditions of soil sites has been greatly reduced.Our north-south cross-border is very large, 5500 km away and across 49 degrees of latitude. So that the topography and climate of the north is different from the south. The protection technology of earthen sites at Northwest Region of China have been more mature, but the protection of earthen sites under moisture circumstances are still unable to resolve. This thesis supervisor to complete the National Natural Science Foundation project as an opportunity to combine the protection of cultural sites of Tianluoshan group, to carry out the suitability of that the use of fine wood bolt reinforced earthen sites under moisture circumstances. The main contents are:1.The thesis will research the physical characteristics of the Tianluoshan ruins soil, and focusing on the shear strength;2.Anchor length study on the ultimate anti-impact and changes of pulling force;3.The research on the ultimate anti-bolt diameter and variation affects the pulling force;4.The research on the ultimate anti-moisture content the impact and changes of the drawing force;5.Anti-stem density influence the pulling force of the bolt limits; fifth step, to explore the optimum moisture content of the soil when the bolt is inserted;6.Explore the soil when the bolt is inserted optimum moisture content;7.To investigate the relationship between the miniature bamboo bolt ultimate drawing force and soil shear strength. |
