Abstract: Landslides cause substantial damage to property, which is seriously hampering social development. With the use of geographic information systems (Arcview), a risk assessment system is established. A 3D geo-information model is drawn into the system. The failure probability of 3D-slope is calculated by using Monte-Carlo method. The risks of life and economic losses are also calculated based on vulnerability analyses. By a case study, the results of the risks of life and economic losses may be crucial foundations for administrant branch based on the 3D geo-information model.

Key words: risk analysis, GIS, 3D-slope model, Monte-Carlo method, failure probability
