摘　　要：某高速公路建成后已经试通车,而城市干道与高速公路过渡段的路面出现开裂和挡土墙外倾变形,同时其路基整体下沉,变形十分严重。通过对路基病害变形特征的分析,弄清了病害发生的原因与破坏机理,采用了对拉锚杆、低压注浆和高压旋喷等工程措施后,治理效果良好。A highway has opened to traffic after construction and, in the transition section between trunk road and the highway, the pavement cracks, the retaining wall tends to incline outside, and the subgrade settles wholly, exhibiting a very serious deformation. Through analysis of these diseases, the causes and failure mechanism thereof were found out, thus the relevant engineering measures, such as counter-pulled bolts, low- pressure grouting, high-pressure jet grouting, were used and got good control effect.

关 键 词：路基挡土墙变形 路基下沉 病害分析 治理措施
