Abstract By the example of one mining tailings dams on Kola Peninsula functionality its guarding dam was investigated. For this purpose, a hydrogeomechanical 3D model created, reflecting geometrical dimensions, geomechanical and hydraulic conditions operation. Using Plaxis 3D, calculations were made for 16 variants increase coefficient transverse filtration water through body. The dependences s...

Vehicle localization in highway tunnels is a challenging issue for autonomous vehicle navigation. Since GPS signals from satellites cannot be received inside tunnel, map-aided essential. However, the environment around tunnel composed mostly of an elliptical wall. Thereby, unique feature points map matching are few unlike case outdoors. As result, it very difficult condition to perform navigati...

A two- (2D) and three-dimensional (3D) multiple-tunnel junctions array is investigated. Device structure and electrical characteristics are described. We present a comparison of carriers transport through devices based on polymetallic grains based on master equation and the orthodox theory. The Coulomb blockade effect of 2D and 3D arrays is observed at low and high temperatures. The conduction ...

this study investigated the performance and aeroelastic characteristics of a wind turbine blade based on strongly coupled approach (two-way fluid structure interaction) to simulate the transient fsi1 responses of hawt2. aerodynamic response was obtained by 3d cfd-urans approach and structural response was obtained by 3d finite element method. aeroelastic responses of the blade were obtained by ...

The routinely used procedure for evaluating tunnel positions following anterior cruciate ligament (ACL) reconstructions based on standard X-ray images is known to pose difficulties in terms of obtaining accurate measures, especially in providing three-dimensional tunnel positions. This is largely due to the variability in individual knee joint pose relative to X-ray plates. Accurate results wer...

The present development situation of 3D and BIM based process model for tunnel design and construction methods has been studied. Tunnel design is generally done using traditional 2D drawing based working methods. As a basement for the research, the new specifications developed in Finland for national BIM requirements for infra sector were used. However, underground tunnels are not yet considere...

A Boundary Element Method (BEM) approach was developed for the analysis of pile groups. The proposed method includes: the non-linear behavior of the soil by a hyperbolic modulus reduction curve; the non-linear response of reinforced concrete pile sections, also taking into account the influence of tension stiffening; the influence of suction by increasing the stiffness of shallow portions of so...

This study conducted an experimental and numerical investigation to examine the pullout behavior of a single pile in sand soil with specific density. The testing model was constructed simulate real-world geotechnical applications where is subjected varying forces. setup involved measuring vertical displacement corresponding different values results were then compared obtained from PLAXIS 3D HS-...

This study investigated the performance and aeroelastic characteristics of a wind turbine blade based on strongly coupled approach (two-way fluid structure interaction) to simulate the transient FSI1 responses of HAWT2. Aerodynamic response was obtained by 3D CFD-URANS approach and structural response was obtained by 3D Finite element method. Aeroelastic responses of the blade were obtained by ...
