Abstract
This is the first in a succession of papers on the risk analysis of pipelines due to multi-hazards in mountain areas. The present paper is focused on the risk of rain-caused landslide which would induce damage to the pipeline. Considering the spatial variations of soil hydraulic properties - such as permeability and pore size distributions - the random field model for unsaturated seepage is presented by the application of the stochastic finite element method. A 3D probability-based slope stability analysis model due to the rainfall by the application of limit equilibrium method is applied. The spatial variation of soil hydraulic properties is analyzed.
