过渡段路基在土柱荷载下的沉降分析

Settlement analysis of transition section of subgrade under the load of soil column

本文结合哈-大客运专线,采用有限元软件ANSYS,计算路基在土柱荷载作用下的工后沉降,6个月后的沉降满足不大于15mm的规定,即预压6个月后可铺轨。

This paper rely on haerbin-dalian high speed railway,through calculating the post-construction deformation under of soil column load.After 6 months,the largest settlement value is less than 15 mm,so we can lay railway.
