Many urban areas in Japan are located on soft ground and there are numerous buildings with pile foundations. Therefore, when dismantling a building, it is necessary to remove the piles (existing piles) remaining in the ground that are designated as industrial waste. One method of removing the existing piles consists of crushing and removing the piles, but there is a problem of vibrations and noise. Therefore, in many existing pile-drawing methods, the outer circumference of the pile is drilled by a steel casing, and the existing pile is pulled out by cutting the boundary between the pile and the surrounding ground. When pulling out an existing pile that exists diagonally, due to the pressure in the soil or an error in the construction, it has been confirmed that the steel casing follows the sloped pile when inserted into the ground. However, the dynamic mechanism of this phenomenon is unknown because the situation in the ground cannot be observed visually. In this study, therefore, an MPS-CAE simulation will be used to clarify visually and quantitatively the dynamic mechanism along an existing pile in which the steel casing is inclined when inserted into the ground, which occurs at actual sites.
