| Abstract: | The article simplifies the roadbed widening model for the common faults in the high-class highway roadbed widening projects. According to the calculation analysis of the practical projects, the article puts forward the detail treatment measures to strengthen the treatment of the old and new roadbed connections, the reinforcement of roadbed, the subgrade treatment of widened roadbed, the control of widened roadbed stuffing and compactness to decrease the settlement difference at the interface of the old and new roadbeds. Its result has the important reference and guiding meanings for the selection, design and construction of treatment measures in the future roadbed widening engineering projects. |
