Quantitative Analysis And Repair Technology Research On The Deterioration Of Wood Structure In Twentieth Century

China wooden structure in the world become an independent school building, has a very high artistic achievement and scientific value. Twentieth Century heritage building because of its special historical background and social atmosphere, has certain particularity, at the same time, it should also take into account the value of its use. For the protection of the wood structure of the heritage building cannot blindly apply the existing repair technology, but should be in a scientific and reasonable evaluation, select the appropriate repair technology or maintenance measures.Paper for wood structure in 20 th century heritage buildings in the preservation of the status quo. Analytic hierarchy process(AHP) analysis method, Delphi method and other means to the dismantling of the wooden structure and combination, step by step evaluation, scoring, finally obtains the overall architectural preservation scores.Through the integration of domestic and foreign research results, put forward the different points of the wood structure of the repair technology options. The full text is divided into the following five parts:Chapter 1, introduction. This paper mainly introduces the research background,research object, method and innovation point. Review the research at home and abroad, analyze the main significance of the topic, and finally form the research framework of the paper;The second chapter, analyzes the China heritage building wood components using the form, and summarizes the degradation phenomena and the reasons of the common;The third chapter, the main use of analytic hierarchy process(AHP) of the architectural heritage of the woodwork was graded, so as to provide a scientific basis for the selection of remediation technology;The fourth chapter, the repair process of architectural heritage is summarized,and the in-depth study of the timber component detection means, repair, and preventive protection.The fifth chapter, taking the protection and restoration of the Red Mansion as an example, the analysis model of the deterioration of the wood structure was evaluated,and the repair technology was optimized.
