摘要
Abstract
In high-speed railway, there are strict and high demands on engineering properties of subgrade filler, especially dynamic characteristics of subgrade bed structure filler. Based on laboratory dynamic triaxial test and field forced vibration test, the dynamic properties of lime-improved Xiashu loess were systematically researched and the feasibility as the foundation bed filler of high-speed railway was evaluated in this paper. The results show that, the lime-improved Xiashu loess has a higher critical dynamic stress value and the elastic and plastic deformation are smaller under the action of the dynamic load, so it meets the demands of foundation bed filler of high-speed railway. However, the mechanical properties of the lime-improved Xiashu loess are affected by related factors, so its water content and compacting factor should be controlled reasonably in its application.关键词
