โœฆ Synopsis

The paper describes a program for automatic analysis of the stability of slopes of any kind, (land slopes, earth dams, embankments, quay walls, etc.) by the Swedish method.

Two factors of safety are obtained, one according to the usual calculationratio of the resistance to the overturning moment, the other as a reduction factor of the strength of the soil, bringing the soil mass to a limiting equilibrium.

Pore pressures are included either by the value of Skempton's B constant or by the height of the piezometric level.

The number of the types of soils may be fourteen or more and pockets of different kinds of soil may be considered. The soils are assumed to be separated by polygonals with a maximum number of 50 vertices and the number of slices to be considered may go up to 100. A flow chart and the "autocode" program are presented. Results for two specific cases are given.

Dynamic stability and time responses are studied for an automatic ball balancer of a rotor with a flexible shaft. The Stodola-Green rotor model, of which the shaft is flexible, is selected for analysis. This rotor model is able to include the influence of rigid-body rotations due to the shaft flexib

Piles used for the stabilization of slopes have to be adequately designed to resist the induced lateral loads due to the movement of the unstable slope. In this paper, a numerical method is presented for the analysis of this problem. In this approach, the piles are modelled using beam finite element
