| description | To illustrate the foundation conditions of gravity dams over 100 m in China and support wavefield analysis at project sites,this paper collects the foundation parameters of 68 gravity dams to analyze the statistical characteristics of elastic parameters and wave velocity.The result shows that the number of dams decreases rapidly with the height,with 3 gravity dams higher than 200 m.The distribution of gravity dams over 100 m is uneven,with a significant number in the southwest area of China.About 93% of gravity dams are with a foundation elastic modulus of 6 GPa to 28 GPa,and the average value is 16.7 GPa.The Poisson's ratios of foundations are from 0.17 to 0.32.The mass densities of foundations are from 2 000 kg/m<sup>3</sup> to 2 900 kg/m<sup>3</sup>.In terms of wave velocities,about 96% of longitudinal wave velocities are from 1 500 m/s to 3 900 m/s,and about 95% of transverse wave velocities vary from 800 m/s to 2 300 m/s.The mean and standard deviation of longitudinal wave velocity are 2 718 m/s and 639 m/s,and those of transverse wave velocity are 1 574 m/s and 383 m/s. |
