Study On Pre-Warning For Public Safety Evens Of Building Heritage In Historic City

Building heritages in historic city are lively carriers of cultural context, as well as valuable fortune of human society. Recent years, our country has attached much importance to building heritage. Without enough advanced science & technology, real-time monitoring and pre-warning system, in addition, more development and less protection, the authenticity and integrality of building heritages were severely destroyed. Therefore, it is emergent to construct pre-warning mechanism for public safety of building heritage in historic city. Based on national key science & technology program, this thesis applied researched on pre-warning for public safety events of building heritage in historic city.Firstly, the overall objective, implementation step, core principle, organization framework, and system structure were analyzed and put forward for building heritage protection in historic city.Secondly, primary disasters and the formation causation were analyzed. The conception of "public safety events of building heritage in historic city" was set up. The identification module of events was put forward based on building safety, environment safety, and feature safety. According to disaster risk theory, the factors, mechanism, content, and flow for public safety risk of building heritage in historic city were studied.Thirdly, sustainable pre-warning system and pre-warning processing were put forward.
