Based on the improved three-dimensional finite element model, this paper studies load transfer mechanism of pile-supported reinforced embankments. The model uses an elastic medium to replace soft soil subgrade, which reduces calculation depth subgrade and improves efficiency model. validity is proven by field test results theoretical results. By changing cohesion, internal friction angle, modul...

It is seen from recent earthquakes that in case of fixed-base foundation system, damped systems have proved to be longing the lifespan structure by lengthening lateral fundamental period leads higher damping comparison assumptions a system. In this study, better understand phenomenon involved soil-pile interaction finite element simulation model developed Abaqus FEA software. The numerical made...

This paper mainly uses the method of model test to study ultimate uplift bearing characteristics a single pile with different length-to-diameter ratios, from distribution laws capacity pile, axial force and side friction perform analysis. The is made PVC pipe, resistance strain gauges are attached both sides pipe. value pipe under load conditions measured obtain working behavior during process ...

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 interaction mechanism between micropiles and soil landslides is comprehensively investigated through static model tests numerical simulations. results show that the deformation damage mode of mainly bending shear damage. Because deformation, cracks appear at rear front pile, respectively, about three times pile diameter from sliding surface. In addition, plastic becomes more severe when app...

Offshore wind-turbine support structures are largely made of steel since monopiles have accounted for the majority installations in last decade. As turbines become bigger, led to an exponential increase material and installation costs. From this point view, use concrete future has been initiated. In study, concrete–steel composite piles investigated. A pre-tensioned high strength pile was place...
