Monitoring and Prediction of the Vibration Intensity of Seismic Waves Induced in Underwater Rock by Underwater Drilling and Blasting

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,soft-ware 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 in-fluence 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.

非均匀光强对曲率型自适应光学系统的影响

在高斯光强和光强存在正态随机起伏情况下,研究了一种37单元的曲率型自适应光学系统对低阶Zernike像差的校正效果,并和均匀光强时的校正效果进行了比较.光强为高斯分布时,光强的不均匀性对Zernike像差的校正带来了一定的影响,对于曲率为零的Zernike像差影响较小,对曲率不为零的Zernike像差影响较大.光强存在正态随机起伏时,对各阶Zernike像差的校正影响较小,曲率为零的Zernike像差的校正效果好于曲率不为零的Zernike像差的校正效果.结果表明在光强起伏不严重的情况下,该37单元曲率型自适应光学系统对低阶Zernike像差可以较好地校正.
