Stress tests of ODP Site 131-808 sediments

Sediments undergoing accretion in trench-forearc systems are subjected to conditions of large lateral thrusting. This stress regime controls the mechanism of faulting as well as the yield and strength properties of the sediment. Understanding them is therefore crucial for the construction of quantitative models of sediment dynamics in convergent margin settings. […]海沟-弧前体系中处于增生过程的沉积物，会遭受强烈侧向逆冲作用的影响。该应力状态既控制了沉积物的断裂作用机制，也决定了其屈服与强度特性。因此，明确上述特性对于构建汇聚边缘构造环境下的沉积物动力学定量模型至关重要。[…]
