The invention discloses ocean engineering rock mass quality scoring methods based on simple testing and fine testing. Aiming at the particularity of ocean rock mass engineering, the invention providestwo specific ocean engineering rock mass scoring methods, and the method comprises the steps: firstly, carrying out on-site point load testing, direct observation and longitudinal wave velocity testing to quickly obtain a preliminary ocean engineering rock mass quality score; subsequently, performing a uniaxial compressive strength test, a quantitative statistical test, a qualitative descriptiontest, a longitudinal wave velocity test, a rock disintegration resistance test and other fine tests on ocean engineering rock mass to form a more accurate oceanographic engineering rock mass quality score. The method has the advantages that the method has sufficient theoretical basis and practical value, rapid, simple and convenient testing and accurate fine testing are combined, reliable scoringparameters and technical support are provided for foundation design and construction of ocean rock mass engineering, operability is high, and the obtained scores are real and reliable.
