摘要
本文简略介绍砂类土地震液化中两个地震因素:地震强度和地震持时的作用,同时还叙述了地震液化判别时“临界区”的存在问题,以及本文最后提出两个适合于工程技术人员使用的液化判别时正确选择近震、远震的实用性方法。
This paper introduces the physical actions of two seismical parameters: Intensity and Earthquake Duration Time. It also presents the problem of 'Critical Area' in the evaluation of soil liquefaction. Finally, this paper suggests two practical methods to be selection of the used for judgement of the far or near eathquake in the site.
