Central heating system as an important part of the lifeline system provides essential heat for the people's daily production and life . Previous earthquake damage showed that , the lifeline system structure and huge damage , such as bridges, pipelines and other facilities in the earthquake . After the earthquake, the destruction of these structures and facilities , often the lifeline engineering subsystem part or total loss of service function , this return to work after the earthquake relief and people's lives to bring tremendous obstacles and serious consequences . However , the heating system as an important branch of the lifeline domestic its land seismic research is very limited , the author based on previous research , combined with the common characteristics of the heating system , water supply, gas system , draw relevant maturity analysis the Damage Analysis heating pipe network system , destruction of grading standards , seismic vulnerability analysis of its earthquake damage assessment technology research . The main content of the paper is as follows : 1, systematically expounded the central heating system Seismic Research , research results and the existing problems . ? 2 , according to the earthquake disaster information , the central heating system damage characteristics analysis of major buildings currently the most widely used central heating system building (structure) , especially the failure characteristics of the heating pipes were described and summary of reasons , and earthquake damage analysis . 3 , according to the central heating system damage characteristics , combined with existing lifeline engineering the earthquake damage grading standards of the central heating system to earthquake damage grading standards . ? 4 , draw water and gas pipe network research , combined with the characteristics of the central heating system itself , seismic fragility analysis of the heating pipe heating pipe network earthquake damage rate , combined with a numerical example is theoretical formula predictive value , compared with the results of experience in water supply network statistics . ? 5 seismic economic loss assessment methods to improve the heating pipe network , based on the model of the pipeline seismic damage rate . Research the cost and repair of the heating pipe network maintenance cost data , economic loss assessment method by a numerical example with the specification of the pipeline compared to verify the reasonableness of the method , recommendations for improvements and regulatory law , to make it more operability. ?
