采用击板法和爆破法结合,成功地在关门山水库工地进行了堆石休内弹性波现场测试和坝体脉动观测,得到了坝体的自振特性和坝体内弹性波速分布及相应的经验公式;在与国外同类试验成果以及室内大型动三轴仪试验成果的广泛比较后,给出堆石材料动力变形参数职值的经验范围。
Using the combination of strike-plate method and blasting method, the on-site elastic wave test of rockfill and the observation of the dam body pulsation were successfully conducted at the site of Guanmen Reservoir, and the natural vibration characteristics and damped elastic wave velocity distribution and corresponding experiences After extensive comparison with the results of similar experiments in foreign countries and the experimental results of indoor large-scale triaxial apparatus, the empirical range of the value of dynamic deformation parameters of rockfill materials is given.
