Primary Physical-Mechanical Characteristics on Marine Sediments from Zhoushan Seas in Sino Mainland
Marine sediment laboratory test model was developed by excavation on site and application of GDS triaxial loading system. The grading characteristics on representative soft marine soil from Wushitang (MS1) and Dongsha Seas (MS2) were studied and the key evaluating indicators, i. e., curvature coefficient CC and non-uniform coefficient Cu were analyzed. Based on the systematically physical-mechanical test data, the constitutive model on step deviatonic-stress and strain development was researched. The result shows the exponential mapping relationship is applicable for stress-strain constitution. The fluid-solid coupling non-linear function was established by spatial pore pressure surface fitting. The key consolidation treatment for soft marine sediments was discovered.
