| Abstract: | The paper adopts the ANSYS finite element program, analyzes the law for the settlement changes of the widening roadbed caused by various roadbed heights and roadbed filler, and points out the relative value can be used as the controlling index in the differential settlement of the widening roadbed, so as to provide some reference for the design for the splicing technology for the expressways in China. |
