The Study On Supporting Structures In Earthquake Emergency Rescue

With the fast development of the economy, three-dimensional traffic system, logistics network, multifunctional building will become the main development trend in the future gradually, thus inevitably causes population unprecedented concentration, wealth highly concentrated, finally makes the city become more vulnerable in the face of disaster. Modern city will appears vulnerable in only tens of seconds during earthquake:like large areas of power shortage, fire rages, traffic jams, the collapse of the housing, a large number of casualties and enormous property losses. Since twenty-first Century, the earthquake disaster happened at home and abroad several large-scale, tens of thousands of people lost their lives in the earthquake. Because of the increasing caused by the earthquake disaster and loss and impact, coupled with the current still can not accurately predict earthquakes, so the focus of global disaster prevention and mitigation work still put in the aseismic design of engineering structure and the emergency rescue work after earthquake. A large number of past earthquake rescue experience showed that 72 hours after the earthquake is the best time for earthquake relief, statistical analysis indicates that about 70% of total casualty is due to not timely and effective rescue during and after earthquake. Therefore, the casualties caused by the earthquake can be reduced effectively through the use of a variety of emergency equipment and effective medical rescue on site, which are linked with the construction of rescue channels by using effective emergency rescue supporting structures that could guarantee the safety of rescuers and rescued person. Therefore the earthquake emergency rescue supporting structures are the key issue in earthquake emergency rescue process.But there are a few of study systematically on such supporting structures for earthquake emergency rescue at home and abroad although their importance is obvious. The study of this research will focus mainly on the following three aspects:(1) model design of typical supporting structure model; (2) numerical simulation of supporting structure model; (3) collective drawings compilation and introduction of supporting structures.The main purpose of this study is to carry out a systematic study on supporting structures by using finite element analysis software ANSYS14.0, combined with the rescue practice experience, and try to achieve a relatively complete and systematic progress on earthquake rescue supporting structures.
