摘要
根据“灾害地质环境调查与评价”项目 1995年 11月、1996年 6月和 1998年 10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究。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 ,也分布有淤泥、淤泥质粘土和粘质粉土 3种粘性土 。
Based on the investigation and analysis results of se diment samples taken during three cruises from Nov.,1995 to Oct.,1998, a compreh ensive geotechnical characteristics study for the bottom sediments in the East C hina Sea oil and gas resource areas was made. It is shown from the analysis resu lts that the sediment texture, shear strength, water content, liquid limit and p lastic limit vary with depth; the sediment types in the areas include sandy soil (medium sand, fine sand and silt) and clayey soil (mud, muddy clay and clayey s ilt), and the physicomechanical properties of sediments are consistent with the associated variations in the soil type.
