Analysis Of The Influence On Great Wall By Jing Zhang Inter-City Railway Tunnel Project

In the new century, with the rapid development of China’s economic construction, railway construction has entered a new development summit. At the same time, the railway traffic vibration harm is becoming more and more obvious. Now, when the high speed railway which between domestic province - province and province - city in the planning and construction are choosed some sensitive route more and more. These sensitive route across and along the way will involve some national cultural relics area, vibration will cause the intangible impact and damage to the cultural relics and historical sites. The premise of adverse effects of how to Effective protection, has become a new problem in the new era of railway lines.In this paper, the research background is in the planning and construction of the Beijing Zhangjiakou intercity railway, according to the railway network planning, through the Beijing the Badaling Great Wall and the water of the Great Wall and other key protection unit, the opening of the railway operation will inevitably to the protection of the Great Wall have harmful effects. Vibration caused by high-speed trains on the Great Wall in terms of ontology, is a typical dynamic problem.Through field investigation, this paper carried out a field investigation and test work, to the Great Wall seismic degree of ontology theory calculation, the train vibration source, physical and mechanical properties of rock mass and the location of geologic parameter information.Finite element dynamic analysis and adopt some general international large software ANSYS and theUniversal Mechanism to make the three-dimensional solid finite element numerical analysis simulation and finite element simulation calculation and analysis, using the three different methods according to the conclusions to get the final conclusion, and put forward the measures and suggestions for the construction of blasting vibration. In order to protect the historical and cultural heritage - the Great Wall, evaluate the influence of Beijing Zhangjiakou intercity train to the Great Wall, is one of the important basis for the line project, is also a theory for the further study of such issues and reference.
