| 摘 要： | 以福清核电站二期详细勘察为依托，采用现场原位测试的方法获取岩体的动、静参数，研究其空间分布特征和相关性。结果表明，中等～微风化岩体的动态参数随深度变化具有一定的规律性，而静态参数随深度的变化规律性不强，但裂隙的发育程度对岩体动、静弹性模量均有明显的影响；在动、静弹性模量关系方面，回归分析结果表明，动、静弹性模量之间具有较好的相关性，动、静弹模的比值不随深度而变化，Ed/Es比值分布在0.9～2.19之间。系统地总结岩体动、静参数的分布规律和其相互关系，对岩土工程设计具有重要意义

| Abstract: | On-site tests in a nuclear power plant are performed to investigate the space distribution and correlation of dynamic parameters and static parameters. It is indicated that there exists a certain rule between dynamic parameters and depths, but not between static parameters and depths. And developed degree of cracks has an obvious influence on both the dynamic and static parameters. In addition, regression analysis indicates that there exists good correlation between dynamic and static elastic modulus. And the ratio of Ed and Es lies in the range of 0.9–2.19, but it does not change along with the depths. The research has important implications on geotechnical engineering designing and construction |
