| 摘 要： | 本文建立了平面应力问题的波动方程，推导了防渗墙（平面应力问题）中瑞利波特征方程，通过算例与平面应变问题中瑞利波特性进行了比较。本文介绍了防渗墙质量检测的一种方法：表面波法，对它的测试原理作了进一步的研究。利用超声波跨孔法和表面波法对某实际工程进行了检测，经过实例证明超声波跨孔法和表面波法相结合可准确检测防渗墙的质量，并且可降低大量的检测费用。

| Abstract: | The dynamic formulations of plane stress problem are founded in this paper. The secular equation of Ray-leigh wave in anti-seepage wall (plane stress problem ). The characteristics of Rayeligh wave are compared between plane strain problem and plane stress problem. Ultrasonic method and surface wave method are first introduced to monitoring the quality of anti-seepage wall and their principles are also discussed. A water conservancy project is monitored by using ultrasonic method and surface wave method. It is proved that the ultrasonic method and surface wave method can accurately monitor the quality of anti-seepage wall;and the cost is little. |
