The invention provides a surrounding rock analysis method based on drill jumbo while-drilling parameters, which comprises the following steps: acquiring while-drilling parameters collected by a drilljumbo in different drilling holes according to a preset time interval, and forming a drilling log containing the while-drilling parameters; judging the category of the current construction project, and obtaining a geological analysis parameter configuration file of the current construction project according to the category of the construction project and the drilling log; and processing the while-drilling parameters based on the geological analysis parameter configuration file, and generating a geological cloud picture of the current construction surrounding rock. Surrounding rock can be analyzed through the while-drilling parameters of the drill jumbo, the characteristics of the surrounding rock can be reflected, and construction is facilitated. Besides, weight distribution is carried outon different while-drilli
