Method and apparatus for controlling the bedding of a post.

摘要

The mass M of the footing (4) supporting the post (1) and the stiffness of the soil/footing bond K determined by the bringing together of the transfer function T(w) computed from the measurement of a vertical impulse f(t) applied to the foot (2) of the post (1) and from the measurement of the corresponding vertical vibrations x(t) of the footing, with the theoretical transfer function (21) of a system (6) having two degrees of freedom by means of so-called modal analysis software. <IMAGE>
