Research on Settlement and Deformation Characteristic and Foundation Treatment Scheme of Expressway Splicing Section
In order to ensure the construction level of expressway reconstruction and expansion,this paper analyzes the splicing method of expressway and the uneven settlement mechanism of new and old subgrade.Taking the"four to six"project of an expressway as the research object,it discusses the application of dynamic compaction method and cement mixing pile composite foundation in the foundation treatment of splicing section.At the same time,the finite element software is used to calculate the post-construction settlement and uneven settlement variation law of the splicing section foundation after treatment.
