Over the years the techniques of civil construction have evolved greatly, along with them the number of inhabitants of large urban centers has increased which has necessitated the need for more robust structural works, be they works for the purpose of urban infrastructure or housing. Large structures need to absorb higher effort from the cargoes for which they were designed, leaving the foundations to transmit these efforts to the ground. Such efforts can be brought about by the very weight of the structure, wind actions, earthquakes and even the abrupt braking of vehicles on the bridge trays. One of the efforts that must be transmitted to the soil through foundations is the horizontal efforts, the main theme of this work. This work presents some of the methods used for the calculation of deep foundations submitted to lateral actions, the bibliographic review presents methods based on the analysis of soil rupture involving the stake and also methods based on the analysis of stake deformations. As a complement, was compared the results obtained by analytical models proposed by Miche (1930) and Hetènyi (1946), with the results obtained by the Ftool and Robot programs, for the calculation of a long stake immersed in cohesive and non-cohesive soil, submitted to a horizontal load applied at its top, which showed small variations between the results for the stresses that occur along the stake stem. The greatest difference was found in the results of the maximum displacements in the top region of the pile due to the differences between the calculation models proposed by the authors and the calculation model inserted in the programs. It was also analyzed a long stake immersed in stratified soil subjected to a horizontal load applied at its top, through a simulation made in the Robot program, which demonstrated the ease of simulating a deep foundation with the use of computational tools through mathematical simplifications. |
