【摘要】 根据近几年来的实际勘探资料，对现代黄河水下三角洲埕北海域的复构三角洲从平面和垂向上做了综合性的工程地质评价，确定了底质类型以粉土为主局部分布有粉质粘土的平面格局和全新世以来沉积四层标准化地层的空间架构，并对其力学性质指标和物理性质指标的关系进行统计，得出相关关系式。更多还原

【Abstract】 According to the data of practical exploration during recent years, comprehensive engineering geological evaluation is made for the multi structural delta horizontally and vertically on Chengdao sea area in modern Huanghe subaqueous delta, a plane pattern where silt dominates and silty clay is distributed locally in the bedding soil and a space structure with four standard statum since Holocene is determined. And relationships of indices in mechanical and physical properties is analysed statistically. At last, relative formulae are obtained.更多还原
