Seismic Safety Evaluation Of Daqing Petrochemistry Subsidiary Company Installments Extending Project

The Daqing petrochemistry subsidiary company daily production 2,300tons urea installments expand can transform the project to belong tothe large-scale industry and mining project.It is a construction project which would arise serious by-disaster after earthquake. According to the interrelated codes and principles in China, a workaround safety evaluation must be performed. This paper presents the major task of workaround earthquake safety evaluation by combining the very properties of the project, including performing earthquake safety evaluation according to theâ…¢grade Standard, Completes expands to the Daqing petrochemistry subsidiary companydaily production 2,300 tons urea installments can transform theproject field site the earthquake security appraisal work, and presenting the 2%, 10% and 63% super probabilities within 50 years of superficial horizontal design earthquake response and acceleration transient( the damp ratio is 5%).According to the planned major task, this paper performs as follows: Regional seismic activity, Regional seismic geological background, Near-field tectonic earthquake and seismic activity, Probabilistic Seismic Hazard Analysis, Artificial seismic,Venues for earthquake engineering,Site soil seismic response calculation.On the basis of a large account of earthquake geology information collection and analyzing the system earthquake activity, by working out the project workaround and adjacent area earthquake conformation, analysis of earthquake active circumstances, analysis of earthquake risk and response, this paper concludes the major earthquake safety evaluation parameters of Daqing petrochemistry subsidiary company daily production2,300 tons urea installments of expanding project workaround earthquake peak values and design earthquake response. The evaluation presents that the workaround intensity of 10% super probability within 50 years is its basic earthquake intensity. The stability and adaptability of this building is good, without any bad geology phenomenon. The evaluation conclusion presents scientific supports for the feasible research of construction, plan, quakeproof and disaster reduction treasures to take.
