利用大洋32航次在皮嘉费他海盆和中太平洋海盆获得的重力活塞柱状样品,在现场进行了含水率、湿密度、微型扭力十字板以及微型贯入试验,获得了深海盆地浅层沉积物的物理力学性质。研究表明,深海海盆沉积物具有较高的含水率和较低的湿密度、抗剪强度、贯入阻力,各项土工参数之间具有很好的相关性,并且随深度呈现一定规律性的变化。
Gravity Piston Cylindrical samples obtained from Daya Feat Basin and the Pacific Ocean Basin on Day 32 were used to carry out on-site water content, wet density, miniature torque crosses and micro-penetration tests to obtain shallow-sea sediments Physical and mechanical properties. The results show that the deep sea basin sediments have higher water content and lower wet density, shear strength and penetration resistance, and have good correlations among various geotechnical parameters and show some regular changes with depth .
