干湿状态下岩石动静弹性参数变化规律及关系

The changing rule of dynamic and static elastic parameters under the circumstances of dry and wet rock and their relationship

以某核电场基岩的花岗岩为研究对象,通过弹性模量和泊松比两种方法测得岩石在烘干和饱和两种不同状态下的弹性参数,并对实测结果进行了对比分析,总结了岩石在两种不同状态下的动静弹性参数的变化规律及动静态系数间的函数关系式,对岩土工程设计具有重要意义。

Taking the granite of bedrock in certain nuclear power plant as research object, the article measures elastic parameters of the rock under two circumstances of drying and saturation using elasticity modulus and Poisson＇ s ratio method, carries out contrast analysis of field measuring results, and summarizes changing rules of rock＇s dynamic and static elastic parameters under two different circumstances and the equations between dynamic and static parameters, which has significanees for geotechnical engineering design.
