| 英文摘要 | One of the most important factors in modeling wave-induced transient pore pressures in coastal zones is the apparent pore fluid compressibility. Nonetheless, existing models for evaluating the compressibility of pore fluids have embraced an unwarranted disregard for atmospheric pressure. This oversight can lead to inaccurate and inconsistent results concerning wave-induced transient pore pressures and associated seabed liquefaction. In this study, the apparent pore fluid compressibility is revisited to address the ambiguities widely found in the literature. The validity and applicable scope of various simplified formulas correlating the apparent pore fluid compressibility and the saturation degree of soil are briefly summarized. Analytical and numerical results are compared against two series of flume experiments to demonstrate the necessity of incorporating atmospheric pressure to accurately evaluate apparent pore fluid compressibility as a function of saturation degree of soil, especially for water depths approximately less than 50 m. Given the challenges associated with direct measurements, the saturation degree of a partially-saturated sandy seabed can be estimated by calibrating measured wave-induced pore pressure distributions against analytical solutions. This approach serves as a feasible parameter for bridging the apparent pore fluid compressibility between conditions with different static water depths and excess pore pressures. |
