DEAL WITH COUNTERMEASURE OF CRACKED ROCK LANDSLIDE

Construction period always depends on the complexity of cracked rock slops which leads to twice change of the plan in the treatment of the K81 high slop on the Jinliwen expressway. Because we considered that the cracked rock slop formed as geological genesis, the guiding principle was to solve the stability of the rock slope caused by poor rock integrity in the first change. When we implemented the project and performed the geological investigation and analysis deeply, we found that the cracked rock slop was caused by ancient landslide, which leaded to the second change of the plan about the slop treatment after the slope had been excavated and some parts of the reinforcement project had been done. The geological condition in cracked rock slops is complex, and the cause of cracked rock decides the characteristic of the globe stability, therefore the investigation, analysis of the geological model and the exploration would due to proper plans to eliminate the hidden troubles in disasters.
