Experimental Study on the Dynamic Characteristics of Post-Earthquake Loess

详细信息   
摘要

The paper studies on the dynamic characteristics of post-earthquake loess for supplying reasonable and reliable parameters of seismic safety evaluation for post-disaster reconstruction in loess area. Through the experimental study on dynamic characteristics of post-earthquake loess in Yongdeng, Gansu Province, the paper discusses on the dynamic characteristics, and the results indicate that there are enormous differences in dynamic characteristics between under dynamic load post-earthquake and the undisturbed loess in Yongdeng area, mainly in decreasing of dynamic modulus of elasticity and evident increasing of residual deformation.
