摘　　要：通过数值模拟、室内动光弹试验、仪器设备组合改进与研制及现场试验,对混凝土截渗墙质量无损检测声波相控技术进行了较为深入的研究。声波相控法能使弹性波能量在某一方向上聚集和增强,并能有效地削减和压制面波及直达波的干扰,凸显反射信号,这些优点为数值模拟和动光弹试验所证实。声波相控技术作为一项检测截渗墙等隐蔽工程质量的检测新技术,具有较大的开发应用价值。It conducts a deeper study on sound phase control technique of non-damage test of concrete cutoff wall quality through numerical simulation,indoor dynamic optical elastic tests,integration,updating and development of instrument and in-situ tests.The method of sound phase control can focus and increase the elastic wave energy on a certain direction and can effectively reduce and control the interference of direct wave and give prominence to returning echo.These advantages are verified by numerical simulation and dynamic optical elastic tests.Sound phase control is a new technique for detecting cutoff wall and other underground works quality.It has greater value of development and application.
