Impact pile driving is a multi-component problem which is associated to multi-directional ground vibrations. At first, vibration is transferred from the hammer to the pile and then to the common interface of pile and soil. This is then transferred to the environment and has great impact on the adjacent structures, causing disturbance to residents and also damage to the buildings. It is of high ...

abstract: The behavior of continuous flight auger (CFA) piles and steel H-section to lateral loading is investigated using numerical analyses supported by field tests. A three-dimensional finite element model load presented. was validated with the results twelve tests performed on CFA installed in two deposits sandy soils. approach proposed this study good agreement response observed tests, thu...

In this paper, a numerical investigation of the effects grout parameters on load response concrete pile-grout systems in soft clay is presented. The study examines influence diameter and depth bearing capacity pile under vertical lateral loads. research findings indicate that grouting can enhance single system by up to 27% loads 51% loads, depending used. This due grout's ability fill voids soi...

stable pile depth in the Snowy River study (SKM 2005) is outlined. The inputs used in the run of the LLP99 model were: • single soil layer, • very high flexural stiffness of pile (1,000,000 kN/m). • pile width = 0.3 m (i.e. wooden pile), • shear strength in the absence of lateral stress (for unconsolidated sand 150 kN/m was used), • effective unit weight of soil (15 kN/m), • active lateral effe...

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 develops an analytical method to calculate seismic bearing capacity of a strip footing, which is located on a slope reinforced with rows of pile. the resistance of passive pile is determined based on normal and shear stress of the soil around the pile, which is then compared to other analytical methods. this comparison indicates an acceptable agreement. the variants of the study incl...

Design of foundations in earthquake prone areas needs special considerations. Shallow foundations may experience a reduction in bearing capacity and increase in settlement and tilt due to seismic loading. The reduction in bearing capacity depends on the nature and type of soil and ground acceleration parameters. In the case of piles, the soil-pile behavior under earthquake loading is generally ...

in the realistic manner, piles are similar to the slender columns that soil around them acts as a lateral support. the piles situated in the liquefiable soil layers, loss their lateral supports due to the liquefaction resulted from the seismic ground motion. in this case, pile has the potency of axial instability similar to the unsupported columns. this instability can lead to the lateral buckl...
