Resumen

This paper describes a new procedure for assessing the ratio between in situ stresses in rock masses by
means of K (K=σH/σv, being σH and σv principal stress) and tectonics for purposes of engineering geology
and rock mechanics. The method combines the use of the logic decision tree and the empirical relationship
between the Tectonic Stress Index, TSI, and a series of K in situ values obtained from an extensive database.
The decision tree considers geological and geophysical factors affecting stress magnitudes both on the
regional and local scale. The TSI index is defined by geological and geomechanical parameters. The method
proposed provides an assessment of the magnitude of horizontal stresses of tectonic origin. Results for
several regions of Europe are presented and the possible applications of the procedure are discussed.
