Abstract

The irregular rock piece is used to test the point load strength of rock at the job site. The BGS formula is established. The Grubbs criterion is adopted to take in or reject dubious data. A complete computer program for point load test is compiled. The reliability and strength ratio of point load method is studied also. Par l’essai des pièces irrégulières, on teste la résistance relative à la eharge de point, la formule de BGS est établie; Utilisation des règlements de Grubbs, on pourrait prendre ou rejeter les données douteuses; Etablir les programmes de calculateur de tous les examens; Rechercher la comparaison de la fiabilité et de la résistance relatives à la charge de point. Vor Ort Messung der Punktlaststarke mit den Proben. Herstellung der Gleichung von BGS. Ausmerzen der zweifelhaften Daten mit Hilfe von Grubbs Norm. Programmierung der Datenverarbeitungen von Messung. Forschung der Punktlast liber Verläßlichkeit und der spezifischen Starke.
