One of the important issues of tunneling in urban areas is the assessment of the impact on adjacent buildings of tunnel construction. Many high rise buildings are supported by pile foundations in major cities. Tunneling activities carried out adjacent to these pile foundations invariably cause ground movements, which in turn will impose axial and lateral forces on the pile foundations. The study focuses on the estimation of ground movements induced by tunneling (both vertical displacements and horizontal displacements) and the imposition of these soil movements on the pile and computation of the consequent pile responses. Tunneling induced behavior of piles was estimated using PLAXIS software. A parametric study was carried out for short pile in sand. Based on the parametric study, design charts were developed for short piles to estimate the tunneling induced behavior of pile easily.

In this project, an experimental study is made on pile pullout capacity, varying the diameter of the pile (d), Length to diameter ratio (L/d), the effect of pile inclination or batter angle (α), nature of the pile surface by placing the pile in cohesionless soils. The experimental values are determined and are compared with case studies in literature. In this project, various literatures on pullout capacity of piles were studied and experiment procedure was derived. Poorly graded river sand was used for cohesionless deposit. The sand is tested for engineering and index properties. Two types of piles, rough and smooth with different lengths were tested at different batter angles. The results are plotted in the graph. These graphs are used for comparative studies of various outcomes of the experiment and results were established.
