摘要
通过阐明Idriss和Boulanger判别法的发展演进及其理论依据,以孟加拉国吉大港卡纳普里河底隧道地质勘察项目为依托,对工区多个断面的饱和砂土地层进行液化判别,并与《建筑抗震设计规范》、《公路工程抗震规范》判别的结果进行对比。结果表明:对于国外工程砂土体的液化判别,用Idriss和Boulanger判别法更为适用。
By expounding the development and theoretical basis of Idriss and Boulanger method,based on a geological survey project of a river tunnel in Bangladesh,the liquefaction discrimination of saturated sandy soil strata in multiple sections of the work area is carried out and the comparison is made with the discriminant results of Code for Seismic Design of Buildings and Specification of Seismic Design for Highway Engineering.The results show that Idriss and Boulanger are more suitable for the liquefaction discrimination of sand soil in foreign projects.
