分析了地震荷载下的岩石动力学特性和试验研究方法，采用RDT-10000型岩石高压三轴仪进行了岩石动力学试验，给出了浙江三门核电站推荐厂址凝灰岩、凝灰质砂岩、霏细斑岩、流纹斑岩的动态弹性模量、泊松比、剪切模量和轴向动载的三轴抗压强度值。这些参数已经应用于可行性研究报告和抗震设计中。

The properties of rock dynamics under the commercial nuclear reactor foundation are very important Parameters in ascismic design. The properties of rock dynamics and test method under earthquake loading are analyzed in this paper. From this, the dynamic elastic modulus, poisson' ratio, shear modulus, and triaxial pressure strength of 4 kinds of rock (tuff, tuff sandstone, felsophyre, rhyolite porphyry) have been given by using the RDT-10000 high Pressure triaxial machine. These parameters have been used in the feasibility report and the aseismic design of the Sanmen Nuclear Power Plant.
