多年来为了解坝基根石情况,常使用测秆(锤)进行探摸,但是费工费时很不安全,而且往往因工程陡峻探摸不成。针对防洪之需要,我们利用水声学原理,设计了一种应用于水下的坝基冲刷探测仪(以下简称探测仪),并经室 Over the years to understand the foundation of the dam foundation, often using straw (hammer) for exploration, but time-consuming work is not safe, and often due to steep exploration project failed. For the needs of flood control, we use the principle of water acoustics, designed a scouring probe applied to underwater dam (hereinafter referred to as detector), and by the room
