A Discussion on Dynamic Characteristics of Undisturbed Loess by Dynamic Triaxial Test
摘要
Abstract
Based on the dynamic triaxial test system and using the fitted wave of the Wenchuan earthquake and 1 Hz constant amplitude sinusoid, the paper compares the results of tests on undisturbed loess samples under different loads and vibration modes but under same saturated conditions. Results of the comparative experiment show ： The stress-strain curves have a similar trend under random seismic loading and constant amplitude sinusoidal loading, but the random seismic loading is more sensitive to failure strength of the undisturbed loess samples under the same stress.关键词
