Several methods are available to predict the ultimate resistance of a pile in clays and sand. Unlike shallow foundations, deep foundations have been designed for specific applications. These applications include: bearing high loads and reduce poor soil is weak, and so forth. There are three different categories (1) Static method, (2) Laboratory Methods. We review the major development in static method and outline new challenges although the including static and dynamic pile load tests are also discussed. The comparison in design methods of pile in the form of charts and tables as well as discussed to design software pile All-Pile are presented in this paper. Keywords: Pile, Deep Foundation, The method design deep foundation, The Pile bearing capacity 1. INTRODUCTION Foundations are essential to transfer the loads coming from the superstructures such as building, bridges, dam, highways, walls, tunnels, towers and for that matter every engineering structure. Generally that part of the structure above the foundation and extending above the ground level is referred to as the superstructure. The foundation turn are supported by soil medium below. Thus, soil is also the foundation for the structure and bears the entire load coming from above. Hence, the structural foundation and the soil together are also referred to as the substructure. The substructure is generally below the superstructure and refers to that part of the system that is below ground level. Thus, the structural foundation interfaces the superstructure and the soil below as shown in Figure 1 and 2. The soil supporting the entire structure above is also referred to as subsoil and/or sugared. For a satisfactory performance of the superstructure, a proper foundation is essential. Foundations are classified as shallow and deep foundation based on the depth at which the load transmitted to the underlying and/or surrounding soil by the foundation as follows.
