摘要
采用PLAXIS有限元软件对不同工况下拓宽路堤进行了非线性有限元分析得出:拓宽路堤的自重会使老路堤产生较大的附加沉降和水平位移,路基模量和土层对路堤变形的影响较大。
Nonlinear finite element analysis is carried out on expanded embankment under different working conditions with PLAXIS finite element software.It is known from analysis that the deadweight of expanded embankment will cause larger additional settlement and horizontal displacement on the original embankment.Subgrade modulus and soil mass have larger influence on embankment deformation.
