项目摘要

The PIs will attempt to understand why submarine slopes fail where and when they do, through numerical modeling that will simulate the evolution of stresses and fluid pressures (and flow) in sedimentary buildups. They propose to use Discrete Element Methods (DEM) to model these processes, inputting laboratory and borehole constraints such as shear strength, internal friction, density and porosity and deriving internal friction, compressive and tensile shear strengths, and elastic modulii through modeling. The focus of the study research will be to attempt to understand the causes of failure in these environments, which is difficult to accomplish through direct observation. Broader impacts include graduate student training, support of underrepresented groups in the Earth Sciences, K-12 outreach, enhanced computational infrastructure, dissemination of results to the broader geohazards community, and the societal benefits of understanding the risk associated with submarine landslide hazards.
pi将通过数值模拟来模拟沉积体中应力和流体压力(以及流量)的演变,试图了解海底斜坡在何时何地失效的原因。他们建议使用离散元方法(DEM)来模拟这些过程,输入实验室和井眼约束,如剪切强度、内摩擦、密度和孔隙度,并通过建模得出内摩擦、压缩和拉伸剪切强度以及弹性模量。研究的重点将是试图了解这些环境中失败的原因,这很难通过直接观察来完成。更广泛的影响包括研究生培训,对地球科学中代表性不足群体的支持,K-12的推广,增强计算基础设施,向更广泛的地质灾害社区传播结果,以及了解与海底滑坡灾害相关的风险所带来的社会效益。
