It is concluded that, first, geochemical data of the surface soils can clearly distinguish two kind of soils, that is, juvenile soils, for example, purple soils, which inherits most geochemical characteristics of the parent rocks or materials, and anthropic soils, the geochemical characteristics of which have been greatly changed as the results of intensive impact from variety of agricultural uses. Second, different soils have typical indicator elements association respectively due to different parent rocks or materials and utilization, such as purple soils, yellow soils (low alkali and alkaline-earth metal contents and pH value), paddy soils (high organic element and heavy metal elements contents) and fluvo-aquic soils (high rock-forming accessory mineral elements contents) and so on. Consequently, it can be suggested that elements association is an important indicator for two key factors (parent materials and anthropic activities) of soil classification. Third, some differences exist between soil genesic classification and result of cluster analysis, because geochemical characteristics of surface soils can not completely represent the foundation applying to soil genesic classification, that is, condition and process of soil-forming, and soil property.

结果表明：浅层土壤的地球化学数据能较好地用来区分两类土壤，即紫色土一类的幼年土壤（在很大程度上继承了母岩、母质的地球化学特征）和受强烈人为活动水耕、早耕熟化的土壤（外来物质的不断加人显著地改变了浅层土壤原有的地球化学性质）；(2)各类土壤因母岩母质和利用方式不同，各具明显的标志性元素组合特征，如紫色土、黄壤（低碱和碱土金属元素和pH值）、水稻土（高有机元素、肥料元素和重金属元素）和潮土等，因此，这些元素组合是土壤分类两个要素的重要参照系；(3)浅层土壤的地球化学特征不可能完整地体现成土条件、成土过程和土壤属性这三个发生分类依据，因此，聚类分析结果与发生类型之间存在一定的差异。

This paper examines the soil characteristic and liquefaction degree of hard shell seams at the subaqueous delta of the Yellow River. Four typical areas were chosen for measuring, testing and studying. The hard shell seam strength was measured by in-situ Proctor penetrometer. Undisturbed soil sample of 1 m long was excavated for laboratory soil property test. Sledge hammers were dropped down freely to hit the load board to simulate the wave force acted on the hard shell seam. The excess pore pressure and strength variation were observed. The liquefaction depth of the hard shell seams at four study areas under different wave storms were calculated by theory.

为揭示黄河口水下三角洲硬壳层的土性特征和风浪作用下的液化破坏状况，选择典型研究区，在现场利用普氏贯入仪测试硬壳层的强度特征，原位取1m原状样进行室内土工试验；利用重锤锤击荷载板的方式模拟波浪对硬壳层的动力作用，通过孔压探头和普氏贯入仪实时监测土体内孔压和振动前后强度的变化；通过理论计算研究硬壳层在不同风浪等级下的液化深度。

On the safe side, we should use active soil pressure and passive soil pressure to calculate the support strength before T increased. That is RA=EA-EP Among them: RA ………… holding strength EA ………… composite force of active soil pressure EP ………… composite force of passive soil pressure Immediately, flexural torque distribution of enclosure wall can be counted. Mmax is the location of shear force zero. Equivalence beam method abridges. No matter which kind of supporting structure form, the key problem lies in the establishment depth of catch point, severity of support and enclosure wall, penetration depth and pit bottom quality of soil property.
