摘要
现代黄河水下三角洲沉积体系中存有许多对工程不利的软土夹层和透镜体，它们主要是由高含水、高孔隙性的粘土质粉砂和粉砂质粘土组成，由于形成时的快速沉积和波浪作用等因素，使其具有明显的欠固结性，且其固结程度随深度变化呈无规律状．另外，因为软土中粘粒含量较高，颗粒问的水胶联结和静电引力与分子引力联结，而使其具有明显的触变性，从而使其较低的强度在受到破坏后也难以恢复．
There are many soft soil intercalations and lenses unfavourable to engineering in the modern subaqueous Huanghe Delta, consisting of highly watered and porous clayey silt and silty caly. The consolidation of the sediments is poor owing to high - speed deposition and cyclial loading. In addition, the mud has obvious thixotropy and low strength which is difficult to resume after destruction.
