CALCULATION METHOD OF STRESS IN WELL STRUCTURES BUILT UP WITH STEEL PIPE PILES AND THE APPLICATION TO SOME PROBLEMS

Calculation method of stress in well structures built up with steel pipe piles is treated by means of Finite Fourier Integration Transforms.The well structure of this kind is supposed to be structure of space beam which are connected to each other by axial joint springs.Discussion is especially focused to an elliptic well having partition walls inside space. Three types of well: circle, square and ellips with two partition walls, are numerically taken up, and the results of the third type are compared with experimental values.
