摘要
Abstract
The wave velocity(Vpr)of fresh intact rock(rock block)is an important parameter for calculating the integrity coefficient of rock mass.The value of the elastic compressive wave velocity of rock mass plays an important role in the evalua-tion of the integrity of rock mass,but its value has the disadvantage of strong randomness.The probability distribution model of the elastic longitudinal wave velocity distribution of rock mass is obtained through statistical analysis of the original test of the same type of rock.Through different probability assurance rates,the upper limit value of the wave velocity of the complete rock mass can be obtained by using the probability distribution model,and the value range of the elastic longitudinal wave ve-locity parameter of the rock can be obtained.Taking the test data of granite in a pumped storage power station as an example,the practical engineering example shows that the proposed method based on the normal distribution of elastic wave parameters of rock mass can provide a reference for determining the integrity evaluation of rock mass in practical engineering.关键词
