In view of the problem that attribute value is given in the form of interval number in the fuzzy multiple attribute decision making, comprehensive ideal scheme decision method based on set pair analysis is adopted to make decision. The method extend the application range of set pair analysis from accurate real number domain to fuzzy interval number field.(More)
3d landslide geological modeling is the prerequisite of geotechnical and engineering geology numerical simulation analysis, and there have not been very direct and efficient software tools to realize this modeling process currently. Taking account of this, a new 3d landslide modeling method is posed from an integrative view in this paper. First, extract the(More)
Reservoir water fluctuation and rainfall are the main factors to trigger landslides in the Three Gorges reservoir area. It is the key to study the landslide three-dimensional seepage under reservoir water fluctuation and rainfall for landslide stability evaluation, disasters prevention and reduction. We investigated the Lijiawan Landslide in the Three(More)
—Soil cave foundation is common in Karst area, which damage would impact the stability of the foundation. Currently, the qualitative analysis of the collapsed mechanism has been done, but few of quantitative. Based on the theory of elasticity and plasticity, the stress condition and influence circle of concentration around the cave is researched. The(More)
