摘要

黄河水下三角洲为细粒粉质土沉积。土体渗透性是海工设计与海床稳定性评价的重要参数之一。在波浪等循环荷载作用下，黄河口海床土渗透系数如何变化尚不清楚。本文利用现场原位振动试验和室内土样振动实验，研究土体渗透系数随所受振动能量的变化，发现循环荷载作用使海床土渗透系数先变小然后持续变大，变化幅值可达4倍多。通过同步测量循环荷载导致的土体容重等的变化，结合试验现象的观测，进一步分析了渗透系数随循环荷载变化的机理。

Abstract

Silt soil sediment in theYellow River subaqueous delta

and its permeability is one of important geotechnical parameters of marine engineering design and seabed stability evaluation. The variation of coefficient of permeability of the Yellow River estuary seabed under cyclic loading

for example

wave

is not clarified now. Vibrant experiments in situ and in the laboratory are carried out to study the variation of coefficient of permeability along with the variation of vibration energy. It is found that the coefficient of permeability of the seabed under cyclic loading declines firstly and then increases continuously; and the extent of the variation is more than 4 times. The variation of bulk density etc. of the soil under cyclic loading is tested at the same time. Combining the observation of experimental phenomenon

the mechanism of variation of coefficient of permeability under cyclic loading is further analyzed.
