Most of the researches in the literature have interested in piled foundations as settlement reducers and external load supports. One of the most famous damage caused by horizontal soil movement is the collapse of 13- storey building in China in 2009 under nearby surcharge loading and excavation works as shown in Fig. Passive pressures and relative soil-pile displacements play an essential role in the behaviour of piled foundations and may induces deflections and bending moments which can cause serviceability problems and even damage to the passive piles and. This kind of loading is caused by lateral movement of the surrounding ground and is called passive loading and the piles subjected to these loadings are known as "passive piles".īuildings with passive piles can be seen on unstable soil layers or nearby excavation activities, pile driving operations, surcharge loads and tunnelling operations (Fig. Some construction activities and natural phenomena induced lateral "hidden loading" on pile foundations.

The software results revealed that the distribution of bending moment along the pile length vary considerably and was in a very good agreement with the real pile behaviour when adopting a variation of soil elastic modulus with depth instead of choosing a constant value. A parametric study was conducted to investigate the influence of soil Young's modulus and soil movement profile on the response of single "passive pile". A good agreement between laboratory and predicted results is observed in the validation analysis. The MohrCoulomb elasticplastic constitutive model was employed for the soil stress-strain behaviour. Embedded pile feature in which the pile composed of beam elements with special interface elements to represent pile-soil interaction is used.
