应力密实化不仅存在于天然土中，也存在于人工模拟和物理模型试验中。这种致密化可以增加稳定性和抗液化性。对八种砂土的一维压缩试验数据进行了分析。从这些数据的应力致密化方程的开发，以估计由于施加的应力变化的密度增加。在评价物理模型试验结果时，如果不考虑应力密实化，可能会导致错误的结论.关键词：应力，密实化，修正，物理试验.
Stress densification occurs in natural soils as well as manmade embankments and physical model tests. Such densification can increase stability and liquefaction resistance. One-dimensional compression test data from eight sands were examined. From these data a stress densification equation is developed to estimate the density increase due to applied stress changes. It is found that stress densification can lead to erroneous conclusions if not taken into consideration when evaluating physical model test results.Key words: stress, densification, embankments, physical test.
