| Abstract: | Uneven settlement happened in soft foundation and road surface in a highway section of provincial road of Henan Province with channel box culvert cracking and the side slope is unstable. The accident section is divided into 4 areas for reinforcement. By grouting reinforcement of roadbed foundation, setting up a slope drainage system and improving the bearing capacity of the foundation, the traffic capacity of the road is guaranteed. |
