中文摘要：
通过现场试验，研究模拟波浪振动导致的黄河口海床表层粉质土重度与强度的变化；通过室内试验，研究了黄河口海床土重度、强度、中值粒径、起动流速随振动能量的变化；将起动流速的试验测试结果与代表性经验公式计算值进行了比较。发现振动导致黄河口粉质土物理力学指标呈现周期性的变化，进而引起起动流速相应的变化；起动流速不仅与土体重度、粒径、强度有关，还与土体承受的波浪荷载振动能量有密切关系；起动流速经验公式计算结果与试验测试值不吻合。
英文摘要：
By means of experiment simulating wave load in-situ, the changes of silt density and strength in the Yellow River Estuary resulted by simulating wave load were studied; by means of laboratory experiment, sea-bed silt density, strength, grains size, CET（critical erosion threshold） vs. vibration energy in the Yellow River Estuary were studied. The results show that due to wave vibration, the silt properties and CET change by wave action in the Yellow River Estuary; the CET is not only in relation to the density, grains size and shear strength, but the energy of vibration load; CET empirical equation could not apply to experiment values.
