CONSIDERATIONS ON THE STABILIZATION OF ROCK SLOPES

SOME CONSIDERATIONS ARE MADE ON HOW FAR GRANITE AND SCHIST STRUCTURES, AS WELL AS THE DEPOSIT CONDITIONS OF THESE ROCKS, ARE DETERMINANTS AFFECTING THE GEOMORPHOLOGIC EVOLUTION AND THE STABILITY OF SLOPES. THE EXAMINATION OF A GRANITE OR A SCHIST IN CUTS, IN NATURAL SURFACES AND IN SETTLEMENTS SHOWS, WHEN THEY ARE NOT TOO DECOMPOSED, THAT THESE ROCKS ARE FORMED BY BLOCKS OF SHAPES MORE OR LESS PARALLELLEPIPED, INTERLOCKED AND CONTACTING EACH OTHER. THE PLANES DEFINING THE BLOCKS OF THE SO CALLED JOINTS AND IN SCHISTS THERE ARE ALSO THE PLANES OF SCHISTOSITY. SOME CASES THAT OCCURRED WHEN THE STABILIZATION OF SLOPES IN GRANITIC AND SCHISTOUS ROCKS WAS BEING PERFORMED ARE ALSO MENTIONED. THE STRUCTURE OF ROCKS AFFECTS THE SHAPES OF VALLEYS. THE NATURAL STABILITY OF SLOPES AND SLOPE STABILIZATION ARE REVIEWED. THE MOST FREQUENT TECTONIC ACCIDENTS OF ROCKS ARE THE SO-CALLED FAULTS AND FRACTURES, CAUSED BY THE MOVEMENTS OF THE EARTH'S CRUST. THE EXISTENCE OF FRACTURES AND THEIR INFLUENCE OVER THE BEHAVIOR OF ROCK BLOCKS ADVISES THE NECESSITY OF IN LOCO MEASUREMENTS OF ROCK CHARACTERISTICS, MODULI OF ELASTICITY, RUPTURING STRESSES, ETC.
