| Abstract: | A finite element analysis shows that the binding site of the low subgrade and structure is characterized by an uncoordinated defermation. Based on the mechanical response analysis results, the failure mode and design status of the binding site are explored in detail, in addition, the indexes and criterion for uncoordinated deformation control are proposed. Then, the design method about the low subgrade structure binding site is established, including the design status, indexes, criterion, process and steps, which offers a reference for the future engineerings in terms of the design foundation, design idea, and technology support as well as the decision making. |
