秦山核电二期工程地基动态参数测试和地基动态模型

DYNAMIC PARAMETER MEASUREMENTS AND DYNAMIC FOUNDATION MODEL OF THE SECOND PHASE OF QINSHAN NUCLEAR POWER PLANT PROJECT

秦山核电二期工程是我国重点建设的大型核电项目。参照国内外的核安全规程,用先进的仪器设备,在该工程场地上进行了全面、系统的地基动态参数测试。这次测试的内容、规模和难度在我国是前所未有的,主要包括用孔内剪切锤激振、爆炸激振和电火花激振等激振方法,进行了四组跨孔测试和二十个钻孔的系统声波测井。最后,根据对测试结果的分析提出了地基岩体的动态模型。本文主要介绍了这次测试工作的测试方案、技术方法和测试成果。

Large scale dynamic parameter measurements were carried out in the site of the second phase of Qinshan Nuclear Power Plant project. The measurement included four sets of cross-hole tests and twenty runs of acoustic logging. This paper presents the technological plan and results of the measurement and dynamic model of the foundation.
