摘　　要：黄土动力特性是黄土地区地质灾害中重点考虑的一个影响因素,因其机理复杂,目前还未有规范对其进行定性的解释。针对目前学术界使用较多的土动强度试验方法,考虑到实际工程工期紧、试验量大的特点,提出了一种测试黄土动强度的新方法,该法具有试验量小、数据处理简单等优点。通过英国GDS动三轴进行试验,论证了该法的合理性与可靠性,对后续科研工作具有参考意义。The dynamic characteristics of loess is a key factor that should be concerned in relation to geological disasters in loess regions. Due to its complex mechanism, till now, there is no codes to carry out the qualitative explanation. In relation to the test methods for dynamic strength of soil often used in the academic circles, with the consideration of short construction period and large amount of tests in practice, a new method was put forward to test the dynamic strength of loess, which has the advantages of small amount of tests and simple processing of data. With the GDS triaxial system, the test was conducted to prove the reasonability and reliability of this method which is of great reference to the later study.
