Earth platforms supported by rigid columns provide an effective solution for embankments founded on thick deposits of soft soils. Nevertheless, the failure mechanisms and associated soil–structure interactions remain inadequately comprehended, particularly structures such as with caps or ground beams. Recent studies have reported sporadic incidents basal instability in column–supported over soil. To gain further insight into this issue, study investigated foundation settlement, mode columns,...
A geosynthetic-reinforced piled embankment situated along a newly constructed high-speed rail line was fully instrumented and monitored to explore soil arching in an equilateral-triangular arrangement of piles with circular cap configuration. During construction, the settlement vertical stress on pile caps subsurface at ground level tensile strain geogrid were recorded. modified analytical model is derived from established concentric arches (CA) elucidate load transfer mechanism,...
The relationship between railway track-bed stresses and speed is essential when performing track foundation design. Current approaches to describe this are typically empirical multiply the static response by a dynamic amplification factor account for effects. This paper develops an alternative method generation instead of numerical simulation. A vehicle–track dynamics model presented, capable simulating subgrade considering random irregularities. First, samples irregularity generated based...
For industrial applications in cold regions, a fly ash-amended soil with lignin reinforcement is introduced here. Predictive models were developed for shear strength based on two ensemble learning algorithms, to facilitate understanding properties limited prior knowledge. First, over 270 unconsolidated undrained triaxial tests conducted the stabilized varying moisture contents, percent fiber, confining pressures, and curing conditions (uncured, 15 days curing, along freeze-thaw actions)....
Retaining walls are structures used to retain earth materials on a slope. Typically, they designed for static loads, but highway and railway infrastructures, vehicle-induced dynamic responses also relevant. Therefore, retaining wall often with factor of safety that is higher than necessary, because it can be challenging quantify the magnitude expected stresses during design stage. This unnecessary increase in material usage reduces sustainability infrastructures. To improve sustainability,...
A monitoring project was implemented in trial sections of the Watang−Rizhao heavy-haul railway. Data were acquired at instrumented track formations and railway retaining wall during 30 passages train operating speeds ranging from 5 km/h to 100 km/h. At formation level, earth pressure cells mounted beneath 10 longitudinally adjacent sleepers, one which installed along with two integrated vibration sensors for vertical acceleration deflection measurements. The different elevations examining...
Asphalt concrete (AC) is a traditional material that used to construct highway pavement and offers the advantages of good bearing capacity, waterproofing, shock absorption, noise reduction. In recent years, AC also has been railway infrastructure as part rapid development high-speed rail in China. The study presented this paper focused on composition mechanical response asphalt (RAC) basis mechanistic models laboratory experiments. According test results, air voids RAC-25 for should be...
In the booming field of nanotechnology, colloidal silica (CS) has been introduced for ground improvement and liquefaction mitigation. It possesses a great ability to restrain pore pressure generation during seismic events by using an innovative stabilization technique, with advantages being cost-effective, low disturbance, environmentally friendly method. This paper firstly introduces molecular structures some physical properties CS, which are importance in practical application CS. Then,...
