Random finite element method (RFEM) provides a rigorous tool to incorporate spatial variability of soil properties into reliability analysis and risk assessment of slope stability. However, it suffers from a common criticism of requiring extensive computational efforts and a lack of efficiency, particularly at small probability levels (e.g., slope failure probability Pf<0.001). To address this ...

In order to estimate proper current land price, various factors such as environment, communication, regulation of land use and so on are established by local government. Road slope is one of the land price factors for land form, and land price is corrected by road slope aspect based on road slope for the north. For example, road slope aspect is corrected so that land price face to northern slop...

During June to October 2000 and 2001 we measured the height, Diameter at Breast Height (DBH) and stand density of Betula ermanii trees at Mt. Mae-Shirane, Japan and the ozone concentration there to explore the relationship between ozone concentration and the decline of B. ermanii trees on the mountain. Height, DBH and stem volume were lower on the southeast-facing slope than on the northwest-fa...

Slope stability analysis is one of the most important problems in mining and geotechnical engineering. Ignoring the importance of these problems can lead to significant losses. Selecting an appropriate method to analyze the slope stability requires a proper understanding of how different factors influence the outputs of the analyses. This paper evaluates the effects of considering the real geom...

Katabatic flows along a planar slope in a viscous stably-stratified fluid are investigated analytically and numerically, with an emphasis on flow features arising from the action of the Coriolis force. Two idealized flow types are considered: turbulent flow along a uniformly cooled slope, and two-dimensional laminar flow induced by a cold strip of finite width running down the slope. In the cas...

Heavy seismic damage tends to occur in slopes when groundwater is present. The main objectives of this paper are to determine the dynamic response and failure mode of sandy slope subjected simultaneously to seismic forces and variable groundwater conditions. This paper applies the finite element method, which is a fast and efficient design tool in modern engineering analysis, to evaluate dynami...
