Formation mechanism and movement characteristic of a high altitude collapse on the No.108 National Highway in west Sichuan Province;

The causes of collapse along Dazhun railway line and preventive measures;

Geological Hazards of Huangluquan Collapse and Its Prevention Countermeasures in Zhangqiu City;

Based on past research,the paper analyzed systematically and comprehensively the natural and artificial factors leading to landslip geo-hazard in Zhaoyuan gold field,Shandong.

Based on the understanding of the mountain disaster in the three gorge reservoir, this article gave a detailed analysis of the landslip, landslide debris flow and the loss of the soil and water, which was caused by mountain disaster.

Through field investigation and analysis,combining with historical earthquake documents,the causes of landform,rift valley and landslip relic of Xionger mountain is studied.

Application of the remote sensing technique to monitor landslides of Hualien debris disaster watershed areas

It s concluded that the cause of rocks landslide is integration of both inside and outside factors,such as the rocks physical and mechanical characteristics,rainfall,weathering,human activities,etc.

The study was implemented by spatial analysis with GIS from landslide sites versus physiographic features,hydrologic features,land-use,and aerial photo interpretation to trace the sediment sources and the reasons attributing to the slopeland hazards.
