Rock physical property-mechanical parameter research method and system based on big data analysis

The invention provides a rock physical property-mechanical parameter research method and system based on big data analysis, and relates to the technical field of rock engineering. On one hand, by constructing the rock physical model based on machine learning, rock physical property parameters can be determined without geotechnical experiments; on the other hand, a huge amount of rock physical property-mechanical parameter relation research is taken as a core, a Python crawler is utilized to obtain rock physical property-mechanical parameter data from the database, a multiple regression analysis method is utilized to process and fit the various physical property-mechanical parameter data of the rock, a multiple regression function is constructed, a mapping relation between the two is determined, and the physical property-mechanical parameter data of the rock is obtained. Therefore, the corresponding rock mechanical parameters can be calculated according to the rock physical parameters, the problem that in engi
