中文摘要：
通过对黄河三角洲海港地区粉质土的室内实验，从物质组成、结构形态和沉积环境的角度阐述了黄河三角洲粉质土前期固结压力的特性，并探讨其含义。通过试验发现，作为一种性质较为特殊的区域性土，黄河三角洲地区广泛存在的粉质土的前期固结压力所表现出的规律与传统的土力学理论并不相符。经分析认为，黄河三角洲粉质土的前期固结压力主要受土的成因、结构和成分的制约，上覆压力的影响甚微。
英文摘要：
By indoor experiments about the silt in the Yellow River Delta, the characteristics of the silt＇s pre-consolidation pressure were studied from points of soil genesis, structure and com- ponent, and sedimentary environment. The studies show that, the silt in the Yellow River Del- ta, as a special regional soil, has a different trend of the pre-consolidation from the traditional theory. And the pre-consolidation of silt is most constrained by soil genesis, structure and component, and is affected by the overlying pressure in little degree.
