APPLICATION OF DSM IN OBSTACLE CLEARANCE SURVEYING OF AERODROME [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 Compared to the wide use of digital elevation model (DEM), digital surface model (DSM) receives less attention because that it is composed by not only terrain surface, but also vegetations and man-made objects which are usually regarded as useless ...

Behaviour of micropiles in heterogeneous coarse soils [PDF]
, 2016 This paper reports on an experimental investigation on the behaviour of small-diameter piles, commonly referred to as micropiles. This particular type of deep foundation is frequently used in many barely accessible Italian mountainous areas, often ...

GEOTECHNICAL INVESTIGATION AT LIGNITE MINES
Mineral Resources Engineering, 1999 Open pit lignite mining provides the energy resources for about 80% of the electrical energy annually consumed in Greece. Optimum open pit slope stability design is related to the minable reserves as well as the cost of mining. This paper presents a geotechnical investigation for the "Tomeas 6" lignite mine at the Ptolemais-Amydeon basin (in northern ...

Numerical evaluation of the pipe-pile buckling during vibratory driving in sand [PDF]
, 2019 The buckling of steel pipe piles during vibratory driving is numerically studied using the Multi-Material Arbitrary Lagrangian-Eulerian (MMALE) method. This method handles the large soil deformations that occur during pile driving and other geotechnical ...
