Using a series of model tests, this study investigated the effect of a passive pile on 3D ground deformation around a laterally loaded pile and on that laterally loaded pile's response in sand. The active pile head was subjected to lateral loads, and the passive pile was arranged in front of the active pile. In the model tests, the distance between the two pile centers was set to zero (i.e., a ...

Relying on a deep foundation pit project in Beijing, using FLAC3D three-dimensional finite-difference software simulation combined with displacement monitoring data verification method, the excavation and three-pile two-anchor rod support system anhydrous sand pebble stratum are systematically analyzed, summed up variation law of formation stress, internal force soil nail, axial bolt, stress pi...

Fibre-reinforced polymer (FRP) is a type of composite material used to provide resistance corrosion when incorporated into piles. However, there gap in knowledge terms the behaviour FRP piles under axial or lateral loading soils. Thus, aim this experimental study assess factors that influence FRPs and load sandy soil. CFRP (carbon-fibre-reinforced polymer) GFRP (glass-fibre-reinforced were test...

Rock-socketed pile is widely used in coastal wharf, Marine bridge, and power engineering, the end bearing function considered more design process. However, lateral friction resistance of rock-socketed piles an important part, load transfer mechanism pile–soft rock interface research focus. In this paper, a comparative analysis was adopted test, ten groups test specimens were made, including fiv...

In this paper, limiting force profile for laterally loaded rigid piles in sand and is differentiated from the on-pile force profile, from which elastic-plastic solutions are established and presented in explicity expressioins. Nonlinear responses of the piles are characterized by slip depths mobilized from mudline and the pile-tip. At the states of tip-yield and rotation point yield, expression...

Post-grouting technology has been extensively used in geotechnical engineering to improve the bearing capacity of various piles, which overcomes technical limitations bored piles and recovers mechanical performance strata. A considerable amount earlier research conducted investigate behavior reinforcement mechanism grouted while very few studies focus on area post-grouting technique. The theore...

ABSTRACT The issue of environmental protection has led researchers to pay serious attention to waste tires. Civil engineers have found that waste tires can increase bearing capacity, earth slope stability, and other useful applications in civil engineering. In this paper, a series of experimental modeling have been performed to investigate the effect of waste tires on increasing the stabi...

alcohol production from molasses can lead to large amounts of wastewater that cause serious environmental concern. it is characterized with extremely high organic loading rate, high turbidity and dark brown color .composting this kind of wastewater is a biothermal aerobic process that during composting heat generated by the composition of the organic material reduces the moisture content of the...
