| 摘 要： | 以具体工程为背景，针对高速公路扩建工程中普遍出现的纵向裂缝问题，采用探地雷达、地震影像等方法检测纵向裂缝处基层，并提出面层纵向开裂的处治方案，最后采用三等水准观测评价处治后效果。结果证明，纵向开型的处治不能仅仅处理面层．应加强基层处治。

| Abstract: | Based on specific project, aimed at longitudinal cracks in highway expansion projects, ground pene- trating radar and seismic imaging method were used to detect the base below longitudinal cracks. The treatment scheme of longitudinal cracks was put forward, and third order leveling measure was adopted to evaluate the treatment effect. The results show that not only surface but also base were treated for the longitudinal cracks. |
