Piled embankments rely upon arching of the embankment material onto underlying piles, thus potentially significantly reducing load on soft subsoil that more generally prevails beneath embankment. Finite-element modelling a piled in plane strain has previously been reported; ‘subsoil' was not explicitly modelled, but represented by vertical stress acting underside This technical note considers extension this work to three dimensions. The results make particular reference prediction at point...
Biaxial geogrid in current research is oversimplified, and the three-dimensional orthotropic nature of biaxial has not been fully understood numerical investigations. A comparative study on three modeling approaches for presented this paper, including isotropic membrane model, truss element model. It shows that model yields practically identical results maximum tension when compared with whereas tends to yield values are approximately 33% larger. parametric pile spacing strongest influence...
Retaining structures with bored piles and temporary inclined steel struts are suitable for the reinforcement of underground projects located in urban areas high-density development as they convenient use earth excavations their leads to considerable savings time cost. However, few data available on foundation pits supported by struts. This paper presents a case study investigate behavior large-scale pit struts, which movement displacement retaining structure reported. The measured results...
Neuroligins are postsynaptic adhesion molecules that essential for specialization and synaptic function. But the underlying molecular mechanisms of neuroligin functions remain unclear. We found Drosophila Neuroligin 1 (DNlg1) regulates structure function through WAVE regulatory complex (WRC)-mediated actin reorganization. The disruption DNlg1, DNlg2, or their presynaptic partner neurexin (DNrx) led to a dramatic decrease in amount F-actin. Further study showed but not DNlg2 DNlg3, directly...
Significance Myotonic dystrophy type 1 (DM1) is a model for RNA-mediated disease in microsatellite expansion disorders. DM1 caused by CTG expansions (CTG exp ) and expression of CUG RNAs that sequester muscleblind-like (MBNL) proteins, while also triggering hyperphosphorylation CUGBP1/ETR3-like factor (CELF1). These proteins regulate developmental transitions RNA processing, so characterized retention fetal processing patterns adults. Although current evidence indicates CELF1 specific...
The British ‘Code of practice for strengthened/reinforced soils and other fills' (BS 8006) was substantially revised in 2010, with a further ‘Corrigendum' 2012. Historically, BS 8006 considered arching piled embankment, based on an interpretation the ‘Marston' equation. 2010 revision included alternative method related to analysis which proposed by Hewlett Randolph 1988, later itself amended 2012 Corrigendum. This contribution considers predictions reinforcement tension using these methods...
This paper presents a finite-element (FE) analysis of the effect subsoil in reinforced piled embankment and compares findings with predictions from theoretical method. It shows that can carry as much 75% arching load for present standard model (pile spacing 2.5 m, geogrid stiffness 6 MN/m, height compression index 0.7). Also, proportion is larger lower value pile spacing, stiffness, height, index. The maximum settlement found to be more sensitive than stiffness. method reasonable agreement...
In 2014, the authors of this paper considered predictions reinforcement tension in a piled embankment from British standard BS 8006 published 2010 and 2012 amended version, compared results with finite-element model predictions. keeping 8006, any contribution subsoil beneath was ignored. The present extends that earlier work by also considering potentially beneficial lightly overconsolidated clay layer, both as simple modification to predictive method. It is assumed there no ‘working...
This paper presents a simplified finite-element model, based on which the arching in highway piled embankments subjected to moving vehicle loads is investigated. The analyses demonstrated that pile spacing was more sensitive factor than embankment height, whose increase from 2·0 3·0 m led 60–68% of normalised maximum settlement at base embankment. effect particular interest, increasing and vertical stress by approximately 23% 19%, respectively, compared static situation. influence height...
The results of a series linearly elastic-perfectly plastic plane strain finite-element (FE) analyses are reported, investigating the arching granular embankment supported by pile caps over soft subsoil. objective research was to contribute further generic understanding in piled embankment, and contribution tensile reinforcement near base embankment. stress state load on subsoil were examined. demonstrate that ratio height centre-to-centre spacing is key parameter determining behaviour....
This paper describes a simplified numerical model for geogrid-reinforced piled embankments considering dynamic loads. Based on this model, the vertical stress acting geogrid is investigated comprehensively and found to exhibit an inverse trapezoidal distribution. An analytical solution embankment under static load then derived equilibrium assumed distribution geogrid. extended by additional induced loads, based Boussinesq equation. However, characteristics of traffic loads (i.e. frequency...
