摘要
主要研究砂土液化作用下,穿越管道的失效机理及其可靠性问题,并相应提出了一些合理的措施和管理方面的建议。论述中引入了灰色理论,较好地解决了地震工程中用模糊数学及概率、数理统计难以解决的灰色问题,并对穿越管道的砂土液化和场地评定做了有效的评判。
The main topic is to make a study on the reliability and invalidity mechanism of traversing pipelines in case of soil liquefaction. Some earthquake engineering problems, such as prediction of seismic site, intensity, frequency, duration and so on are solved by using grey theory. This paper also deals with the soil-liquefaction and field-assessment and introduces a new way called grey relationship analysis.
