Relationship between Mechanical Properties of Rock and Seismic Wave Velocity of Sanmen Nuclear Power Engineering
The planned Sanmen Nuclear Power Plant is located at Sanmen City, Zhejiang Province. The main exposed bedrock on the site is the Upper Jurassic Period strata, the lithology is tuff sandstone and andesite basalt, and the dike is felsophyre, owing to the rock was suffered different degree weathering, its mechinanical properties have some difference. According to in-situ investigations, drilling, sampling, mechanical property test of rock samples, the physical mechanical indexes of all kinds of lithologic rocks with different weathered degree were statistics comprehensively. At the same time, single-hole and cross-hole seismic wave test of the site and strata lithology were studied, the relationships between mechanical characteristics of rock and seismic wave velocity with different strata lithology and different weathered degree rock were established based on the analysis of site geological conditions. The static and dynamic parameters of different weathered degree rock mass were deduced, and also the relationship between athe average value of shear wave velocity and longitudial wave velocity with different weathered degree rock mass were established. The design parameters of nuclear power plant were given, The reliable basis is provided for the foundation design and earthquake prevention of Sanmen Nuclear Power Plant, China.
