Seismic Risk Analysis In Downtown Areas Of Chongqing

Chongqing lies in the upper stream of Yangtse River with a dense population. Nowadays, with the Three-Gorges-Project construction as well as West Development, it is of urgent need to solve such issues as how to improve urban capabilities of earthquake resistance and disaster reduction in order to adapt these measures to future urban construction and planning together with national economic development. And it is noteworthy that as the youngest municipality, Chongqing is an area that bears special tectonic settings and earthquake conditions for strong and medium earthquake activities. Meanwhile, attention should also be paid to the possibility of earthquakes induced by reservoirs. Therefore, it is of great significance for urban earthquake resistance and disaster reduction, economic construction and social sustainable development to conduct seismic risk analysis in Chongqing and to determine reasonable criterion of earthquake resistant protection.Since this thesis zeros in on seismic risk analysis in downtown areas of Chongqing, the main contents and corresponding conclusions are as follows:â‘ Seismic Environmental Survey and Data Preparation Collect and sort out the current data of earthquake geology, prepare all materials and information flatbase needed in the research, and investigate the main seismotectonic situations and earthquake seismicity characteristics influencing downtown areas of Chongqing.â‘¡Research into the Influence of Earthquake Induced by Reservoir on Seismic Risk Analysis in Downtown Areas of Chongqing Analyze the effects of earthquake induced by Jiangkou Power Station Reservoir in Wulong, Chongqing and Three Gorges Reservoir of Yangtse River on seismic risk analysis in downtown areas of Chongqing, and conclude the latent hypocenter which plays the biggest role in seismic risk of the downtown.â‘¢Partitioning Latent Hypocentral Zones and Setting Seismicity Parameters Analyze and sub-partition latent hypocentral distributions affecting downtown areas of Chongqing, and respectively present their relevant seismicity parameters based on seismicity characteristics of Chongqing Area.â‘£Research into Attenuation Relation of Earthquake Motion The attenuation relation of earthquake motion in Chongqing can be attained according to Conversion Intensity-Range accompanied by establishing attenuation...
