| 摘 要： | 以某绕城高速公路扩建项目软基加固工程为依托，运用有限元数值模拟研究了扩建工程在不同工况下的地基加固效果，同时对开挖方式、开挖坡度、固结度、加宽宽度、软基深度、软基压缩模量等新老路基差异沉降问题的影响因素进行了全面分析，得到新老路沉降的演化规律。

Numerical Analysis of New and Old Subgrade Settlement Characteristics in Highway Extension Project |
| |
| Abstract: | Relying on the soft soil foundation reinforcement works in a ring expressway extension project as an example, the foundation reinforcement effects under different working conditions were studied by finite element simulation. Simultaneously, the factors influencing differential settlement of new and old subgrade, such as excavation method, excavation slope, consolidation degree, widening width, soft foundation depth, soft foundation compression modulus, were analyzed comprehensively. By this way, the evolution law of new and old roadbed settlement was concluded. |
