The use of piles is a well recognized form of slope stabilization. Pile foundations are also often driven through slopes to support structures such as bridges. In pile-slope interaction analysis, the types of lateral loading divide analyses into two main categories, namely piles under lateral loading from supported superstructures called "active loading," and piles subjected to lateral soil movement caused by soil liquefaction or unstable slopes induced lateral spreading where piles are subject to pressures from soil movements, termed "passive loading." The purpose of this research is to clarify pile response under the two different mechanisms to add to current knowledge on pile-soil-slope interaction analysis.

520 $a The use of piles is a well recognized form of slope stabilization. Pile foundations are also often driven through slopes to support structures such as bridges. In pile-slope interaction analysis, the types of lateral loading divide analyses into two main categories, namely piles under lateral loading from supported superstructures called "active loading," and piles subjected to lateral soil movement caused by soil liquefaction or unstable slopes induced lateral spreading where piles are subject to pressures from soil movements, termed "passive loading." The purpose of this research is to clarify pile response under the two different mechanisms to add to current knowledge on pile-soil-slope interaction analysis.
520 $a To better understand pile-slope interaction mechanisms, a series of non-linear finite difference analyses using the commercially available computer programs FLAC and FLAC3D are presented. Plane-strain slope stability analyses using the strength reduction method are studied first without the existence of piles. Embankment slope deformation analysis focuses on lateral spreads induced by earthquake loading on weak or liquefied foundation layers underlying embankments. Both single piles and pile groups subjected to lateral deformations or passive loading are subsequently studied to understand the mechanics of interaction. Arching effects arising from soil plastic flow around the pile shaft are observed and discussed, together with the effects of pile spacing and soil type. The results of plane-strain analyses (rigid piles) are extended to a study of 3-D pile-slope interaction analyses from active loadings. The effects of embankment slope angle on ultimate lateral soil resistance are evaluated by the "p-y" curve approach and the influence of pile spacing evaluated. Pile response is then considered for lateral spread or passive loading where an embankment base layer is liquefied or comprises a weak soil. Sensitivity studies show that the use of active pile p-y curve characteristics may be inappropriate for prediction of passive pile response.
