The underground energy geostructure represented by the pile is one of key paths for cooperative development space and geothermal energy. Because its advantages low cost, high efficiency no extra occupation space, it has become a feasible alternative to borehole heat exchanger. change in temperature field surrounding ground not only affects geological environment but also influences thermomechan...

The subsea anchor piles of offshore wind power floating platform structures are mainly subjected to uplift and horizontal loads, this paper focuses on the case loads. A three-dimensional numerical simulation study pullout characteristics suction in clay layers was carried out reveal movement state during pile pullout, range depth at point where is achieved (referred as range), relationship betw...

The tandem compound piles are a combination of granular column in the deep section and concrete pile shallow section. This method effectively utilizes consolidation densification effects column, as well cementation strength material. acts path, aiding surrounding soil. On other hand, prevents bulging deformation that commonly happens columns during field construction. To study bearing capacity ...

In order to deeply study the mechanism of prestressed anchor anti-slide pile, an indoor model experimental device was developed, and a finite difference particle flow numerical analysis slope cable pile established based on reinforcement project in mountain road slope. Based force displacement characteristics influence prestress cable, inclination angle width column spacing landslide, height na...

The foundation pit engineering is a work with large amount of use and high difficulty coefficient. It necessary to ensure the deformation soil in control range safety whole structure pit. In this paper, support project Shijiazhuang City, Hebei Province taken as research object, numerical analysis method used simulate pile-anchor First Section fourth section horizontal displacement value deep se...

– We study the filling process of a two-dimensional silo with inelastic particles by simulation of a granular-media lattice gas (GMLG) model. We calculate the surface shape and flow profiles for a monodisperse system and we introduce a novel generalization of the GMLG model for a binary mixture of particles of different friction properties where, for the first time, we measure the segregation p...

– We report the first experimental measurements of the contact number distribution between randomly packed granular right cylinders (rods and disks) as a function of aspect ratio. The average coordination number 〈z〉 for cylinders varies smoothly with aspect ratio rising from 〈z〉 ∼ 6 for aspect ratios close to one to 〈z〉 ∼ 10 for large aspect ratio. Additionally, our measurements demonstrate the...

We present experiments showing that a granular system of small beads does exhibit ageing properties : its maximum stability angle is measured to increase logarithmically with resting time, i.e., the time elapsed before performing the measure. We show that humidity is the crucial ingredient responsible for this behaviour : while ageing effects are important at intermediate humidity, they disappe...
