孔中电火花震源在核电厂波速测试中的应用
|
摘要
岩土层波速特别是剪切波波速是核电厂场地评价和设计最重要的参数之一,通过原位测试手段获得高精度的波速数据是核电厂勘测中的重点和难点之一。相对于人工孔中机械震源,孔中电火花震源具有发射能量强、频率高、一致性好等优点,本文介绍了跨孔波速测试方法和孔中电火花震源的原理,并以南方某核电厂最重要的核岛区和泵房区跨孔波速测试为例,分析了孔中电火花震源的测试效果和特点。
The shear wave velocity of nuclear power plant geotechnical layer is one of the most important parameters for site evaluation and design input,so how to obtain wave velocity data of high precision by methods in-site tests is the most important and difficult in nuclear power plant survey.Related to the mechanical source in hole,spark source in hole has the advantages of strong emitted energy,high frequency and good consistency.In this paper,taking the cross hole wave velocity tested in nuclear island and pump room area of a nuclear power plant in south China as an example,the cross hole wave velocity test method and the principle of spark source in hole are introduced,and the test result and characteristics are analyzed.
