Abstract

Abstract : China is an ancient civilization. History has left us with a rich cultural heritage, of which ancient cultural sites account for a large proportion. As far as the current scientific research and technology are concerned, due to the particularity and complexity of the humid environment, the protection of ancient cultural sites in the humid environment is still an important topic before us. The research topic involved in this article is about the application of composite nano-calcium-based materials for the reinforcement and protection of soil sites in humid environments. Combined with the development of the research content of this article, the research thinking of the thesis is also adjusted accordingly, making the analysis and solution of the problem clearer. The first is a conceptual study, expounding the relevant concepts in this article. The main purpose is to sort out and study the reinforcement and protection measures and methods of relevant sites and ancient cultural sites, as well as the classification, characteristics, and protection value of ancient cultural sites. Through the analysis and research of these aspects, the composite nano-calcium bases for ancient cultural sites in the subsequent humid environment is proposed based on material basic information. The second is a descriptive research, qualitative and quantitative analysis of humid environment. On the basis of summarizing previous researches, this paper mainly conducts qualitative and quantitative analysis on the judgment of humid environment, the influence mechanism on ancient cultural sites, and the main diseases. Then, it is analytical research, studying the main diseases and causes of the underground palace site in the engineering case, and it is concluded that it is mainly affected by the combined effect of the characteristics of the site's soil and the environment. Through the collection of data from the site survey, field test, and indoor experiment of the underground palace site, the preservation status of the site is collected, and the disease problems faced by the site were analyzed, making it more difficult to protect. The main problem facing the protection of soil relics in humid environment, that is, the research focus, is the research on the development and applicability of reinforcement protection materials. This article attempts to explore the protective effect of composite nano-calcium-based materials on wet sites. Practical research was conducted to verify the feasibility of composite nano-calcium-based materials in practice through indoor site soil simulation. After the completion of a series of experiments, the applicability and compatibility of the composite nano-calcium-based material to strengthen the wet site soil was verified through data analysis, data collection, and mechanism discussion. The experimental results show that the sample with a solid content of 0.4% composite nano-calcium matrix has better salt and alkali resistance. Moreover, the unconfined compressive strength growth rate of 0.4% of the samples has a qualitative improvement over other solid content samples.
