The harm and prevention of landslide from Fushun West open Pit Mine, the largest in Asia

There are many methods for landslide hazard reinforcement. Generally, different reinforcement methods are adopted according to different landslide rock and soil properties, instability modes and external construction conditions. The main reinforcement methods include active rockfall protection net, spray (grouting) method, anti-slide pile reinforcement, retaining wall, anchor rod, prestressed anchor cable, steel grid beam, etc. In addition, slope cutting and load reduction, ground and underground drainage, etc. The above methods are combined with comprehensive treatment and other measures.

3, landslide disaster man-made response measures

When a landslide occurs, the following measures should be taken:

(1) When the landslide occurs, you should run to the sides or high ground perpendicular to the sliding direction, and avoid running up or down the sliding direction.

(2) Do not stay in a low place with thick soil under a steep slope of Rolling Stones or a large number of deposits.

(3) When the landslide slides as a whole and cannot run to both sides, holding a solid fixed object is also a self-rescue measure.

(4) When encountering long-term rainfall or heavy rain, we should be alert to the occurrence of debris flow; If the debris flow occurs, do not run along the debris flow ditch, should run to the hillside on both sides of the ditch bank.

(5) Should try to run out of the building, to the open area, while protecting the head, do not return to the landslide area in a short time to stay in residence, to avoid secondary disasters.

(6) When escaping, abandon all items that affect the running speed, and carry communication tools to facilitate external contact and help.

(7) Timely reporting of the disaster situation to the government or relevant units is conducive to disaster relief and mitigation of disaster losses.

Iv. Conclusion

Due to the complexity of landslide geological material and its engineering, as well as the diversity of environment, the study of landslide stability and the prediction of landslide disaster have always been a very challenging field, and also a scientific and engineering problem to be solved urgently. In recent years, with the development of modern computing technology and landslide information monitoring technology, the application of modern mechanics in the field of landslide engineering safety has become more and more mature. Based on numerical simulation, combined with monitoring information and efficient large-scale parallel computing technology, landslide disaster prediction and early warning have been preliminarily realized. It is believed that the difficult problem of accurate prediction of landslide disaster will be completely solved in the near future.
