| 摘 要： | 根据2001年6月的航次调查及随后的沉积物样品的试验室分析资料，从物理性质和力学特征各方面对东海油气资源区海底沉积物进行了综合工程地质特征研完。发现本区沉积物结构、剪切特征、含水量和液塑限随深度的变化而变化；本区海底沉积物类型既分布有中砂、细砂和粉砂3种砂性土，也分布有扮质粘土、淤泥质粘土和粘质扮土3种粘性土，沉积物的物理力学性质与相立的土类性质相一致。

| Abstract: | Based on the geologic survey data in June 2001 and the subsequent sediment analysis data, the engineering geologic characteristics of sea bottom sediment in the East China Sea oil and gas resource area were studied. It is shown from the study results that the sediment texture, shear feature, water content, liquid limit and plastic limit in the area vary with depth, 3 types of sandy soil (including medium sand, fine sand and silt) and 3 types of clayey sand (including silty clay, muddy clay and clayey silt) are distributed in the area, and the physicomechanical properties of sediment are consistent with the properties of the associated soil types. |
