Ours is a country with thousands of years of ancient civilization , the human legacy in the history of the development process all kinds of antiquities, ancient buildings and sites, which for thousands of years . However , a long time, such as natural and man-made factors, historical heritage has withstood earthquakes and other natural disasters, serious invasion of the use of rail transport , but also for the safety of ancient buildings and sites have adverse effects , several thousand years of history of ancient buildings and the ancient ruins , the current local damage occurred or have been frequent instances of collapse , conservation is imperative. In this paper, there are two thousand years of history of Luoyang Han Hangu Pass Customs House affected by the train running instances of cracking damage as the research object , the measured and theoretical research carried out for the protection of ancient buildings provide reference . This paper studies include: vibration field measurement and analysis of ancient buildings vibration simulation analysis, seismic response analysis . At present, China 's ancient architecture assessment has not developed standards , the paper provides methods and conclusions are available for reference to ancient architecture protection workers . Main work is as follows : 1. Hangu Pass vibration damage on qualitative analysis , gives off floor cracks qualitative analysis of the status and cause cracking . 2 Luoyang Han Hangu Pass tower for the study, for the Longhai railway line induced vibration on the ground floor and the top of the Hangu Pass off the vibration test, analyze propagation of vibration caused by the train , and frequency distribution characteristics , combined with the corresponding vibration control standards to evaluate the vibration of the site ; 3 . finite element analysis software ANSYS, SOLID45 element simulation with external brick and rammed earth part brick in contact with the main structure , the model boundary conditions using Combin14 spring combination unit , set up off floor three-dimensional finite element analysis model ; 4 . Customs House modal analysis, get off the first seven floor model order frequency , period and mode shapes ; 5 . through the Customs House structure model input El-Centro wave, Tianjin wave time history response analysis, evaluation of the seismic performance of Customs House .
