| 摘 要： | 无论从以往大地震的经历还是未来潜在地震危险的角度,唐山地区都是一个研究液化的良好的实验场,对其可液化场地获取符合国际标准的、代表目前国际上液化势衡量指标发展趋势的CPT测试结果,对积累液化研究基础数据、研究液化前后场地的抗液化性能变化以及发展新的液化预测方法应是有意义的工作。本文采用国际标准的CPT技术对唐山地区可液化场地进行实地勘察测试,得到了锥尖阻力和侧壁摩阻力这两项新指标,提出了可液化场地剪切波速构造,同时利用系统的优势,得到了可液化场地锥尖阻力与剪切波速间的关系式,分析了可液化场地CPT剖面和剪切波速特征。几个方面的分析表明,给出的结果具有可靠性。

| Abstract: | Both from the past experience of strong earthquakes and the future potential of the seismic hazard, the Tangshan region is a good testing place for researching liquefaction. The CPT tests on the liquefiable sites represent the trend in the liquefaction study and it is quite valuable to perform the international standard CPT tests on the liq-uefiable sites in the Tangshan region. It is also a meaningful job for accumulating data of liquefaction, developing the new method for the prediction of liquefaction and studying the changes of the properties of the sites before and. after liquefaction by using the CPT indexes. In the paper, the liquefiable sites in Tangshan are investigated with the advanced CPT technique and the tip resistance and the friction resistance for the sites are presented. The shear wave velocity structure of the Tangshan region and the relationship between the shear wave velocity and the cone tip resistance for the liquefiable sites in the region are established by using the advantages of the testing system. The characteristics of the CPT and the shear wave profiles for the liquefiable sites in the region are attained. The analy-ses of the results are made and it has been proved that the results in the paper are reliable. |
