Seismic Safety Evaluation Of Daqing Petrifaction Company Ethene Extending Project

The 800 000 tons ethane extending project of Petrifaction Filial Factory in Daqing is a large 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 the II grade Standard, completing the workaround earthquake safety evaluation of Daqing Petrifaction Chief Factory high pressure polythene rebuilding project, and presenting the 3%, 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: evaluating the earthquake active circumstances, evaluating earthquake region and adjacent workaround geology conformation, analyzing workaround earthquake risk, surveying workaround and testing ground wave velocity, analyzing workaround earth layer response, and conforming the design earthquake dynamic parameters. 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 Petrifaction ethane extending 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.
