摘要

摘要: 黄河水下三角洲的地质勘察揭示了海底浅表地层发生的各种灾害地质现象。以风暴浪导致海底土体液化观点,结合土体动力三轴试验、波浪水槽试验,对黄河水下三角洲浅表地层土体的液化发生条件、形成模式、液化土体运动以及地层发生的重新层化问题进行了分析,指出黄河水下三角洲的灾害地质由于风暴浪导致海底粉质土液化运动而形成,液化后土体运动形式与波浪运动一致,液化土体运动造成的土颗粒分异而使地层重新层化,并初步指出了风暴浪导致海底土体液化在地学、环境、工程等方面的研究问题。

Abstract: The records of geological disasters have been observed through geological investigation on the Yellow River subaqueous delta.Incorporated with the data of dynamic triaxial tests and wave flume experiments, as well as boundary conditions,the forming mechanism and the motion of the liquefied soil were discussed in this paper.The sediments formed after silty soil liquefaction under storm waves will be restratified. The liquefied soil will move in phase with the wave,leading to differentiation of the soil particles. A comprehensive discussion is provided with respect to geological,environment and engineering consequences of storm-induced liquefaction.
