| Abstract: | A finite element analysis is performed for a hollow pile by considering the interaction between the soil and the pile. The vertical ultimate loading capacity is calculated. Some measures such as laying geo-technical composite materials in cracks; increasing soil elastic modulus and cohesion; and filling the side of pile with gravel concrete and so on are proposed. The influences on the loading capacity are discussed in detail. The theoretical analysis can be taken as a reference to the engineering application of hollow piles. |
