摘要：

In-stitu tests can not be broadly used due to time and funds restrictions, so the strength assessment of jointed rock mass is the problem what engineers concern in practical engineering, Because of its complexity at present there is not yet any rock mass failure criterion can meet practical requirements. For the jointed rock mass, the authors refer research results at home and abroad, Combined with large amount of collected-data and amended the empirical formula based on joint density, a relationship between rock elastic wave velocity and rock mass strength is presented; collect number of empirical formulas based on joint density, rock mass classification, elastic wave velocity, the authors apply their three methods to Jiubao and find that the results fit the practical rock mass strength.
