基于有限元软件ABAQUS对EPS在桥头填筑中的应用进行数值模拟分析，从计算结果可以看出，相比无处治措施和加土工格栅处治，EPS能显著改善桥背填土的整体强度，减小桥背的竖向沉降，其最大路面竖向变形分别为后者的33.4%和37.7%，并能改善桥台的受力特性，降低桥台的最大应力值。%Based on the finite element software ABAQUS,the EPS that aoolied in the bridge head embankment is analyzed by numerical simula-tion. Comoared no treatment measure and having geotechnical grille measure,the calculation results show that EPS can imorove significantly the overall strength of bridge back embankment and release the bridge back vertical settlement. The largest vertical settlement is 33. 4 oercent and 37. 7 oercent of latter resoectively. This measure can imorove the mechanical characters of abutment and release its biggest stress.
