Based On Protection Unit And Accounts Units Classification Of Metro Design Theories And Methods

Subway engineering is an important part of civil air defence works, has been called air-defense trunk road vividly. Subway is backbone strength of urban rail transit.We may be attacked with nuclear weapons, Biological weapons and Conventional weapons in war. We also may suffer from Secondary disasters in the city after be attacked. Subway can guarantee the safety of traffic, transfer personnel and transport goods. But ,with the pluralistic development and military pattern of constant changes, world metro became synonymous with high-risk buildings gradually, faced all kinds of forms of terrorist threat all the time.At present, the standard of metro design, structure design and calculation stay in preventing shock damage of nuclear weapons which did not hit directly outside, and defending against biological weapons when the war warning mechanism startup, by considering the subway construction overall protective. But the purpose and meaning of this topic research is:How can the stations finish conversion of peacetime and wartime quickly, and how to divide the explosion-proof unit, and how to design and calculation, when the subway by terrorist threat and attack., in new domestic and international situation. Subway has to transfer personnel and transport goods safely and timely, when the threat and danger comes.The main content of the paper :Find out the solution of protection unit and explosion-proof unit rationally divided , in metro design, by studing various design standard.This paper will take construction project as the research object, and Starting from design. Based on theories of subway station terrorist attacks quantitative risk model, conventional weapons explosion calculation, explosion isolation and wall reinforcement technique, the paper will establish a method of metro design, which comply with the new situation and the new requirements.The research content of this paper as follows:1.3.1 Rationally divided protection unit by corresponding analysis, and based on a variety of normative research.1.3.2 Corresponding measures which against terrorist attacks, in protective units.1.3.3 Set the station the key protective parts and against violent unit, from the internal.1.3.4 The actual engineering application.1.3.5 Taking protective reinforcement measures for already construction project.Find out the hazards, rationally divided protective single, clear stations internal key protective parts and accounts unit settings, through the analysis and research on risk quantification model.Design related geomantic electricity, computation or checking the direct hit of conventional weapons, in the structural design. So as to improve the ability of subway anti-terrorism, meet the new situation home and abroad anti-terrorist requirements.
