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。本文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。
The geological survey of the Yellow River submarine deltas reveals various kinds of disastrous geological phenomena occurring in the shallow epicentral submarine. In this paper, the liquefaction of seabed soils caused by storm waves was analyzed. Combined with the triaxial tests of soil motions and wave flume tests, the liquefaction conditions, formation modes, the movement of liquefied soil bodies and the occurrence of strata in the subsoil of the Yellow River subaqueous delta The stratification problem is analyzed. It is pointed out that the disastrous geology of the underwater sub-delta of the Yellow River is formed due to the liquefaction of subsoil silty soil caused by the storm surge. The liquefied soil behaves in the same manner as the wave motion, and the soil particles in the liquefied soil differentiate Stratified the strata and initially pointed out the research problems on the liquefaction of submarine soils due to storm waves in geology, environment and engineering.
