The electro-hydraulic servo loading system was applied to make cyclic loading tests for fractured rock-like specimens. According to the results of the fatigue test, the power function model was used to fit and analyze the test data, and the fitting degree of the curve was determined by the correlation coefficient, and the result was fitted well. The main factors influencing the fatigue life of specimens were analyzed. The upper limit stress was the most important factor affecting the fatigue life of specimens. Under the same conditions, the specimen had a shorter fatigue life when being applied by higher upper limit stress; the rock of different types and strengths not only had different fatigue life, but also had the different sensitive degrees between the fatigue life and the upper limit stress; the fatigue life of specimens was significantly influenced due to different initial damages.

El sistema electrohidráulico de carga servo se aplicó para realizar pruebas de carga cíclicas para muestras de roca fracturada. De acuerdo con los resultados de la prueba de fatiga (resistencia a la fatiga), el modelo de función de potencia se utilizó para ajustar y analizar los datos de la prueba; el grado de ajuste de la curva se determinó mediante el coeficiente de correlación, y se ajustó el resultado. Se analizaron los principales factores que influyen en la resistencia a la fatiga de las muestras. La tensión límite superior fue el factor más importante que afectó la vida a la fatiga (resistencia de fatiga) de las muestras. En las mismas condiciones, el espécimen tuvo una vida a la fatiga más corta cuando se aplicó por un límite superior de tensión; la roca de diferentes tipos y fuerzas no solo tuvo una vida a la fatiga diferente, sino que también tuvo diferentes grados de sensibilidad entre la vida a la fatiga y la tensión límite superior; la vida a la fatiga de los especímenes fue significativamente influenciada debido a diferentes daños iniciales.
