【摘要】 通过室内静三轴试验,对黄河水下三角洲埕岛海域沉积物———粉土的剪切特性进行了研究。比较了粉土在低围压和高围压下的剪切变形特性和强度特性。试验结果表明,粉土在低围压(10,20,30,40 kPa)下的应力应变曲线和高围压下的应力应变曲线总体趋势基本一致,但在不同围压下其抗剪强度存在差别。更多还原

【Abstract】 The shear properties of silt in Chengdao^’s sea area under different confining pressures were studied through triaxial compression test.The test results demonstrate that the trend of the stress-strain curves of silt under low and high stress levels are simillar,but the shear strength parameters are different under different confining pressures.更多还原
