China has a long history of civilization, our ancestors left numerous descendants of ancient cultural relics. The earth is the ancient heritage sites and is part of the carrier. But classical cultural relics protection has been a subject of research and challenges and problems: long natural role, environmental factors cause secondary damage protection process, coupled with artificial incentive to the development of modern civilization, urban and rural construction, farmers, and life has caused a lot of damage the edge of the ancient ruins and its surroundings condition occurs intensified. However, site protection is divided into soil under the humid environment of ancient ruins arid environment protection and the protection of ancient sites, but focuses on the protection of the ruins soil under wet conditions, learn the ancient ruins of an arid environment protection, and environmental protection at home and abroad about the drought has matured. Plus some synthetic organic and inorganic chemicals, many tests to prove the chemical protective material in a humid environment, the site has a good anti-leakage effect of reinforcing effectThis paper summarizes the humid environment at home and abroad on the basis of chemical materials in the course of research and conservation status of the soil on the site to protect the development of applications, in Zhejiang Tianluoshan soil sites, for example,through the ruins Tianluoshan engineering properties of soil analysis, soil ruins material analysis of the composition of the soil of the site to understand the physical and chemical properties, on this basis, with the four chemical hardener for indoor reinforced soil samples tested and analyzed cure. The main contents are as follows:1 Review the ruins of soil reinforcement protection research status at home and abroad.2 For domestic and humid environment protection material reinforced earthen sites were analyzed.3 Tianluoshan important analyzes of soil properties and soil engineering ruins ruins material composition and preparation of the research process control soil dry soil density and moisture content.4 discusses the domestic academic earthen materials selection principles and strengtheningcommon soil reinforcement ruins protective material performance.5 PS reinforcing agents using TEOS, methacrylic resin, silicone and other chemical curing agents with a unified incorporation of soil(soil moisture Tianluoshan control 15%, 25%,35% and dry density control 1.1g/cm3,1.2g/cm3,1.3g/cm3) for reinforcement,conservation7 d, 14 d under natural conditions and constant temperature and humidity conditions, after28 d, using direct shear tests, unconfined compressive strength test and soil samples before and after the change in color matching to evaluate the strengthening effect; and do the same batch of sample water content and dry density in both the conservation 28 d curing conditions were weathering test(water stability test) to evaluate the mechanical overall sample performance and durability to Comparison of four kinds of curing agent is more suitable for the protection and strengthening ruins Tianluoshan control the curing agent performance criteria.Experimentally obtained results are:After TEOS reinforced soil reinforcement agent ruins soil, the soil around the penetration site of soil reinforcement effect, color matching, compressive and shear strength, weather resistance, and microstructure are greatly improved, and Description This kind of reinforcement material is a viable soil reinforcement material ruins, and under suitable conditions and moisture conservation strips and curing time, can increase the effect of curing agent in the soil, but also for the protection of soil reinforcement ruins research and practical works made some reference.
