单孔声波测试及其工程应用应注意的几个问题
|
摘要
单孔声波测试是岩土工程勘察的重要原位物探测试项目。在测试方法和仪器样参数的选择、弹性纵波的识别、完整性系数的计算等方面以及测试结果的工程应用方面,测试人员不易掌握,常出现争议。笔者就波列包含的地质信息的应用、波速与完整性的关系问题进行探讨,以抛砖引玉,共同提高勘测技术水平。
borehole acoustic testing is an important in situ geotechnical engineering geophysical testing project.But during the test and test methods and equipment layout parameters selection,elastic wave identification,integrity coefficient calculation,and test results of engineering applications,such as wave column contains geological information and the application of the wave velocity and integrity of the relationship,testers not easy control and very questionable.Therefore,it is necessary,the above problems are discussed,with wants to improve investigation technology level.
