确定了影响地震期间砂土液化（或循环流动性）潜力的重要因素，并提出了一个考虑这些因素的液化潜力评估简化程序。可用的现场数据有关的液化或非液化行为的砂在地震中组装和性能评估使用简化的程序进行比较。有人建议，即使是有限的现场数据可以提供一个有用的指导，其他砂矿床的可能性能，提出的数据的方法提供了一个有用的框架，用于评估过去的经验，在地震过程中的砂土液化，简化的评估程序提供了一个合理的好手段，以前的现场观测扩展到新的情况。当更高的准确性是合理的，简化的液化评价程序可以很容易地补充特定土壤的测试数据或地面反应分析，以提供更明确的评价。
Significant factors affecting the liquefaction (or cyclic mobility) potential of sands during earthquakes are identified, and a simplified procedure for evaluating liquefaction potential which will take these factors into account is presented. Available field data concerning the liquefaction or nonliquefaction behavior of sands during earthquakes is assembled and compared with evaluations of performance using the simplified procedure. It is suggested that even the limited available field data can provide a useful guide to the probable performance of other sand deposits, that the proposed method of presenting the data provides a useful framework for evaluating past experiences of sand liquefaction during earthquakes and that the simplified evaluation procedure provides a reasonably good means for extending previous field observations to new situations. When greater accuracy is justified, the simplified liquefaction evaluation procedure can readily be supplemented by test data on particular soils or by ground response analyses to provide more definitive evaluations.
