All underwater drilling and blasting operations generate seismic waves. However, due to a lack of suitable vibration sensing instruments, most studies on the propagation of seismic waves have been limited to shorelines near construction areas or wharfs, whereas comparatively few studies have been conducted on the larger seafloor itself. To address this gap, a seafloor vibration sensor system was developed and applied in this study that consists of an autonomous acquisition storage terminal, software platform, and hole-plugging device that was designed to record the blasting vibration intensities received through submarine rocks at a given measurement point. Additionally, dimensional analyses were used to derive a predictive equation for the strength of blast vibrations that considered the influence of the water depth. By combining reliable vibration data obtained using the sensor system in submarine rock and the developed predictive equation, it was determined that the water depth was an important factor influencing the measured vibration strength. The results using the newly derived equation were compared to those determined using the Sadowski equation, which is commonly used on land, and it was found that predictions using the derived equation were closer to the experimental values with an average error of less than 10%, representing a significant improvement. Based on these results, the developed sensor system and preliminary theoretical basis was deemed suitable for studying the propagation behavior of submarine seismic waves generated by underwater drilling and blasting operations.

所有水下钻探和爆破作业都会产生地震波。然而，由于缺乏合适的振动传感仪器，大多数关于地震波传播的研究仅限于施工区或码头附近的海岸线，而对较大的海底本身进行的研究相对较少。为了解决这一差距，本研究开发并应用了一种海底振动传感器系统，该系统由一个自主采集存储终端、软件平台和孔塞装置组成，旨在记录在给定条件下通过海底岩石接收到的爆破振动强度。测量点。此外，尺寸分析用于推导考虑水深影响的爆炸振动强度的预测方程。通过结合使用海底岩石传感器系统获得的可靠振动数据和建立的预测方程，确定水深是影响测量振动强度的重要因素。将使用新导出的方程的结果与使用陆地上常用的Sadowski方程确定的结果进行比较，发现使用导出的方程的预测更接近实验值，平均误差小于10%，代表着显着的进步。基于这些结果，开发的传感器系统和初步的理论基础被认为适用于研究水下钻爆作业产生的海底地震波的传播行为。
