Genesis Analysis of the Landslide in Lanzhou and the Prevention and Control |
| |
| Abstract: | The landslide in Lanzhou, as a giant old landslide in cross-bedding rock, is of large scale, multi-stage and multi-slide, and subject to repeatedly sliding. Herein this landslide were analyzed from the aspects of genesis, features and safety, and then it was divided into two stages to take precation measures respectively. According to the actual situation, it was determined to use the countermeasures, such as normal anti-slide piles, prestressed anchor-cable anti-slide piles, anchor cable frame, intercepting and drainage ditch, sinkhole backfill, to ensure the safety and stability of the landslide. |
