9312707 Voyiadjis This research is to develop an accurate constitutive model for the remolded soil slurry at the front of the cutter head of a tunnel boring machine. The material in this highly deformed region will be considered as a Cosserat continuum, and the results implemented into a finite element type computer code. The experimental and numerical results obtained in this work will assist in the development of underground space. ***

本研究旨在建立隧道掘进机刀盘前端重塑土浆的精确本构模型。材料在这个高度变形的区域将被视为一个Cosserat连续体，并将结果实现为有限元类型的计算机代码。本工作所获得的实验和数值结果将有助于地下空间的开发。＊＊＊
