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)
In this paper, we report molecular kinetic analyses of water spreading on hydrophobic surfaces via molecular dynamics simulation. The hydrophobic surfaces are composed of amorphous polytetrafluoroethylene (PTFE) with a static contact angle of ~112.4° for water. On the basis of the molecular kinetic theory (MKT), the influences of both viscous damping and(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 concentra-tion around the cave is researched. The(More)
Highly efficient second harmonic generation (SHG) bridging the mid-infrared (IR) and near-IR wavelengths in a coupled hyperbolic metamaterial waveguide with a nonlinear-polymer-filled nanoscale slot is theoretically investigated. By engineering the geometrical parameters, the collinear phase matching condition is satisfied between the even hybrid modes at(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)
