- Abstract:
- In this paper,the data of earthquake disaster and the evaluation on economic loss are collected,disaster-characteristics is studied,the law of economic loss is summarized,experiential models of evaluation of earthquake disaster loss are picked up.On the basis of these jobs,one method of first-step evaluation on economic loss is put forward.The experiential model of earthquake casualty is put forward by studying on the relation between the casualty and earthquake magnitude.According to the fast-measured data of earthquake site and time,the laws of intensity-distribution got by studying the characteristics of historical intensity,the range of earthquake stricken area and those of different evaluation-ranges can be carved up.Thereby,the area of house buildings in the range can be counted from the earthquake emergency response database,or estimated by the proportion of the house possession per person and the population gained from statistical yearbook.Experiential damage ratio of buildings(disaster index matrix)can be picked up by studying the historical building disaster.Loss ratio can be selected from <Post-earthquake field works-Part 4:Assessment of direct economic loss of earthquake disaster>(GB/T18208.4-2005).Replacement unit price of various kinds of house buildings can be collected from the local government.So far the loss of house buildings can be estimated quickly by following the evaluation principle of house building.Other loss can be reckoned by the proportion of the other loss to the house building loss of an event.With the accumulation of the information and field investigation,the earthquake loss result of first-step evaluation should be adjusted actively in order to getting an approximate result.
