Problems solved by technology
A large number of actual measurements show that the dynamic stress generated by ancient buildings under the action of industrial vibration is far less than the static stress caused by their own weight (about 1~3%). Therefore, the possibility of damage to ancient buildings caused by dynamic stress generated by industrial vibration is extremely Tiny, but often due to the overall inclination caused by dynamic strain, the ancient architectural structure loses its stability
Therefore, the anti-seismic method of modern buildings cannot be used to solve the problem of anti-industrial vibration of ancient buildings.
[0004] At present, some papers on anti-industrial vibration of ancient buildings have been published at home and abroad, but most of them stay in the analysis of the dynamic characteristics of ancient buildings, and there are no reports related to cracks and inclinations of ancient buildings.

Embodiment
[0031] The Drum Tower is located at the northernmost end of Beijing's central axis on Di'anmenwai Street, Beijing. It is an important symbol of ancient urban planning in my country. It was first built in the eighteenth year of Yongle in the Ming Dynasty (1420), and after repairs, it was listed as a national cultural relic protection unit in 1996. The Drum Tower is built on a city platform of 4 meters, with a construction area of 2736.27m 2 , is an ancient building mainly made of wood. Entrusted by the Beijing Bell and Drum Tower Cultural Relics Research Institute, on-site measurement and theoretical analysis were carried out on the overall inclination (horizontal dynamic strain) of the Drum Tower under the vibration of surrounding traffic vehicles.

The invention relates to the field of historic building structure protection, and particularly relates to a method for determining integral inclination of a historic building structure under the effect of industrial vibration. The method comprises steps of measuring on site the horizontal velocity response V[0] of the highest point of the historic building structure and the horizontal velocity response V[01] of the highest point of the bearing structure; selecting the equivalent shearing elastic wave velocity V[S] according to the type of the historic building; measuring on site the shearing elastic wave velocity V[S1] of the bearing structure; calculating the integral horizontal dynamic strain [epsilon][S] of the historic building structure according to horizontal velocity response V[0] of the highest point of the historic building structure and the equivalent shearing elastic wave velocity V[S]; and calculating the horizontal dynamic strain [epsilon][S1] of the bearing structure of the historic building according to horizontal velocity response V[01] of the highest point of the bearing structure and the shearing elastic wave velocity V[S1] of the bearing structure.
Description
technical field [0001] The invention relates to the field of protection of ancient building structures, in particular to a method for determining the overall inclination of ancient building structures under the action of industrial vibration. Background technique [0002] my country is a country with ancient cultural relics and a large country of cultural relics. It has 38 world cultural heritage sites and 2,348 national key cultural relics protection units. These heritages are the witness and symbol of the 5,000-year Chinese civilization and the treasure of the motherland. However, with the continuous development of infrastructure construction, industrial vibration sources such as high-speed railways, expressways, and urban rail transit (subway, urban rail) have increased rapidly. The impact and harm of ancient buildings such as palaces, palaces, pavilions, and ancient pagodas have also intensified. Judging from the operation of the built rail transit (subway, urban railw...
