摘要：
We developed a way of using ultrasonic waves to monitor soil moisture and groundwater levels as a countermeasure against slope failure caused by heavy rainfall. This paper proposes a complete embedding installation method for the ultrasonic detector. In addition, the ultrasonic transducer frequency needs to be higher for the new method. An experiment using a high-frequency ultrasonic transducer showed the method to be effective.
