| Abstract: | The paper points out the settlement calculation of the widening of old roads is the most essential problem in the roadbed widening projects,adopts the stress superposition at the joints of the new and old roadbeds to calculate the additional stress,analyzes the maximum settlement point for the new and old roadbeds,indicates the settlement volume for the new roadbeds with various widening ways,and analyzes the settlement of different joint ways,so as to improve the accuracy of the calculation for the settlement value of the new and old roadbeds. |
