Urban Earthquake Evacuation Place Construction Planning

In recent year, the nature disasters has occurred frequently in the world wide, especially the earthquake, it cause the huge damaged to the people and their life, and it already get the attention from all of the countries for this un predicable natural disasters. Therefore, in order to reduce the damage which cause by natural disasters-especially the earthquake, most of the countries try to find out the strategy to against this natural incidence, so, as an important process when earthquake happed-the emergence Shelter's planning and construction can be very helpful to every countries. And now, a lot of countries has stated to built and plan the emergency shelter system, however, our countries this aspect of theory system isn't that good as others.In this situation, this assignment will mainly focus on the discussion of emergency shelter's construction and planning, space layout and so on.First of all, the basic concept, classification, characteristics and functions of the shelter have been defined, according to the basic concept of the place. Second, this paper summarizes the study on the scale of shelter construction at home and abroad, analyzes influencing factors, presents three kinds of estimating methods on shelter scale and defines the scale of shelter construction based on those methods. The closed shelter is comprehensively evaluated and the Spatial Arrangement of the shelter is defined, based on setting up the comprehensive evaluation index and the principle of Analytic Hierarchy Process. Divide the responsibility zones of the closed shelter according to the principle of OVD and WVD, to ensure that the public can enter the shelter immediately. The correction to shelter arrangement design are made based on comprehensive plan, physical relief and the Social and Economic Developing conditions of the city.In the end, take the emergence shelter's planning and construction of Xian yang city as the example, and to examine this theory and method, in order to provide the benefit for the layout of shelter.
