| 摘 要： | 许多水库大坝,特别是土、石坝,由于长年自然因素和人为破坏,普遍存在渗漏现象.为了维护水库的正常使用,对水库大坝的隐患进行检测,显得尤其重要.采用弹性波法中的垂直反射波法和瞬态面波法,利用坝基缺陷可能造成的反射波场和速度变化特征,给出了综合检测水库土、石坝基缺陷情况的方法技术.通过实践,验证了采用综合方法技术进行检测的有效性和实用性.

| Abstract: | Many dams, especially for those made up of soil and stone, are full of leakages because of long term destruction by the nature and human. In order to maintain dam's use, exploring dam's hidden problems becomes especially important. Taking the methods of the perpendicular reflection and the instantaneous status Rayleigh wave in elastic wave, and using possible changes of Reflection wave field and velocity caused by the blemish of dam, the authors present methodology and techniques for exploring foundation soil's and stone's blemish under the of dam. The effectiveness and practicality of the technique has been verified with the engineering examples. |
