EAGER PROPOSAL: Earthquake Rupture Experiment at DUSEL Homestake

该项目的目的是支持正在进行的S4初步设计过程，以开发DUSEL Homestake断裂过程设施计划的地震和断层实验，作为NSF主要研究设备和设施建设（MREFC）计划的一部分。提出的工作有两个主要目标：(1)为在DUSEL Homestake进行动态滑动成核和传播实验提供关键的理论和数值分析；(2)进行实地研究，以便在拟议的实验设施范围内找到适合动态滑动重新激活、成核和传播的现有断层和节理。了解这些断层和裂缝对于DUSEL项目规划至关重要。

The purpose of this project is to support the ongoing S4 preliminary design process to develop the earthquake and fault experiments planned for the Fracture Processes Facility at DUSEL Homestake as part of the NSF Major Research Equipment and Facility Construction (MREFC) initiative. The proposed work has two main objectives: (1) to provide theoretical and numerical analyses critical for the development of the dynamic slip nucleation and propagation experiment at DUSEL Homestake; (2) to conduct field studies in order to locate existing faults and joints suitable for reactivation, nucleation, and propagation of dynamic slip within the scope of the proposed experimental facility. Understanding these faults and fractures is critical for DUSEL project planning.
