新旧路基差异沉降路面力学响应研究

Research on Pavement Mechanical Response under Discrepancy Settlement between the New Roadbed and Old Roadbed

通过数值模拟计算,研究了高速公路改扩建新旧路基不同差异沉降对路面结构疲劳破坏机理和路面结构受力的影响,为相关工程的设计和施工提供参考。

By using numerical simulation, the influence of the differential settlement between new roadbed and old roadbed on pavement stress and fatigue rupture in reconstruction and extension project is investigated,the research results can provide reference for the design and construction for related projects.
