项目摘要
Destabilization scenario of breakwater due to an earthquake and a tsunami was revealed. In the huge earthquake, after the large and long earthquake motion caused the liquefaction with increasing excessive pore water pressure, the breakwater was settled. The breakwater received tsunami force after the earthquake acted. The bearing capacity of the breakwater was loosed due to the decreased of the ground strength. Moreover we discussed on the performance of the breakwater by use numerical simulation result of tsunami inundation depth with damage level of the breakwater.Scours on the seabed due to tsunami causing reduction in bearing capacity of structures were examined by open-channel flow, overflow and seepage flow in rubble mound. During water flow, the vertically upward hydraulic gradient along with excess pore water pressure was generated in the saturated ground. The liquefaction-like phenomenon was observed in the ground.
地震和海啸导致防波堤失稳的情况被揭示。在大地震中,大而长的地震作用导致液化,超孔隙水压力增大,防波堤沉降。地震发生后,防波堤受到海啸力量。由于地基强度下降,防波堤的承载力出现松动。此外,我们还利用海啸淹没深度的数值模拟结果和防波堤的损坏程度来讨论防波堤的性能。通过明渠流、溢流和渗流来检查海啸对海底的冲刷导致结构承载力降低。在瓦砾堆中流动。水流过程中,饱和地面产生垂直向上的水力梯度和超孔隙水压力。在地下观察到类似液化的现象。
