| 摘 要： | 砂层震动液化问题是哈达山水利枢纽工程首要的工程地质问题。根据工程勘察取得的大量试验资料,通过标贯、GJS原状取砂、OYO 3000系列密度测井及瑞利波测试等综合方法,对砂层震动液化问题进行了深入的研究,为坝基加固处理提供了重要依据。其中瑞利波测试技术用于砂土震动液化是一个新的尝试。

| Abstract: | Shock liquefaction of sand layers is a principal engineering geological problem for the Hadashan water conservancy project. An in-depth study has been carried out on it through numerous tests and comprehensive analysis, including SPT, GJS undisturbed sampling, OYO-3000 density log and Rayleigh wave measurement. The obtained results provide an important basis for dam foundation treatment. In this study, the Rayleigh wave measurement technique is first used for assessment of shock liquefaction of sand layers. |
