PI将在桑迪亚实验室的高压密封环剪切装置中进行一系列实验,其孔隙压力可与巴巴多斯和南开吸进棱镜的凹槽相媲美。实验将探索高应变和保留的高孔隙率在滑脱带共存的假设。来自巴巴多斯和南开的模拟和天然样品将通过各种应力路径、孔隙压力和应变率承受高剪切应变。
英文摘要
The PI will perform a series of experiments in a high-pressure sealed ring-shear device at Sandia Labs with pore pressures comparable to the decollements at Barbados and Nankai accretionary prisms. The experiments will explore the hypothesis that high strain and retained high porosity can coexist in the decollement zones. Analog and natural samples from Barbados and Nankai will be subjected to high shear strains through a variety of stress paths, pore pressures and strain rates.
