| Abstract [eng] |
In the master’s thesis investigated the influence of axial force for pier berth pile. Checking what displacements occur when the pile gets hit by a ship. How these displacements are affected by pier superstructure axial force size. The work carried out in a static numerical modelling and experimental pier pile test and simulation. In the theoretical part literature reviewed on the pier construction, external effects acting on the structure (hydrostatic water loads, wave loads, dynamic load, performance axial and split loads). Also discussed metal properties and soil characteristics. In research carried out in the pier structure numerical simulations by changing the dynamic shear force adding location, increasing the size of the axial force and changing soil characteristics. Compared how results change doing different calculation models. Made an experimental model and calculated dynamic shear force that affects the model. During the experiment measured displacements and mechanical vibrations. Also researched soil layers and ground layers elastic modules. Also made and experimental model for the calculation of the pier, adapting the received results of soil properties and used loads. All results taken together and displayed graphically. After completing all the experiments and modulating, it has been researched that axial force has a big impact on pier berth. |
