碩士 / 國立臺灣海洋大學 / 河海工程學系 / 95 / This research, from the marine geotechnical engineering viewpoint, the monitoring of the pore water pressure of seabed and wave height in-situ were collected and discussed to the pore water pressure characteristic and wave statistics analysis in seabed soil under irregular wave action. And also comparison with the laboratory simulation test to understand the relationship properties.
In general, in laboratory tests, no matter model-scale-down test, irregular wave simulation, the disturbed soil or external force are applied, will be considering the limitation of the laboratory space and time conditions. The monitoring in-site to get the monitor data no matter to theory, numerical simulation, laboratory test, there have a higher reference value for engineering practice. Therefore, it deeply understands pore water pressure in the seabed soil excited under wave loading. It could be an important topic, challenge and valuable study of nearshore geotechnical engineering
This study, the waves of sea area by monitoring from Golden Coast in Tai-Nan was collected. The wave form of the change water level by superposition shows a normal distribution. It could be indicated that the water level signal can be analyzed with the linear wave or the frequency spectrum.
Concerning above the monitoring of wave induced the pore water pressure within the seabed, the results of calculation of Yamamoto wave theory and the cyclic triaxial tests in laboratory could indicate that by using of the wave theory formulae derived under limitless depth seabed and pore water completely saturation, to evaluate the seabed of dynamic pore water pressure after the wave through the break zone.
It found that the dynamic pore pressure induced by wave loading is underestimated tendency. But the decay curve of compared with the monitoring data and theory calculation have same tendency. It is decreased as depth dimensionless of increasing.
