| 中文摘要: |
| 开挖道路对既有路面结构造成直接破坏，以致行车荷载作用下的受力模式发生变化，而现有模型对新模式下的结构变形和应力计算存在缺陷。因此，正确认识开挖后道路特征，建立新模式下结构变形和应力计算模型是掘路修复理论分析的基础。在三维有限元分析成果基础上，最终确定掘路修复的设计方法与参数。 |
| 英文摘要: |
| The existing pavement structure is damaged by the digging directly, so the force model is varied under the traffic load, but the existing calculation model is defective for the structure deformation and stress calculation under the new mode. Therefore, recognizing the pavement characteristic after the excavation and establishing the calculation model for the structure and stress calculation under the new mode is the basis for theory analysis of pavement rehabilitation. The design method and parameters of excavated pavement rehabilitation is presented based on the 3D finite element analysis. |
