| Abstract: | For the expressway widening engineering treated with small non-sand concrete pile,a finite element calculation model is established.The deformation features of the ground work and filling area treated with small non-sand concrete plies in expressway widening engineering,and the influence of the changes of pile length on the settlement of foundation and filling subgrade are analyzed.The results have certain guiding significance to the widening of expressway. |
