摘要
通过建立有限元分析模型,研究列车移动荷载作用下横观各向同性场地土时域振动传播规律。研究表明,土体的振动总体上随着距离轨道中心线距离的增大逐渐减小,但在土体中显著存在振动加强区域,需要加强对沿线建筑物的减振研究。
Based on the finite element model, vibration diffusant character is studied in transverse- isotropy soil under moving train load. Calculation examples show that vibration in soil gradually decreases along with gradual deviation away from railway line, and there obviously exists an enhanced area ,so the study about reducing vibration for building along the railway line is needed.
