RIA: Failure Criteria of Reinforced Soil and Analysis of Reinforced Soil Structures

本研究的目的是为了更好地理解加筋土的破坏；并提出了一种新的加筋土体建模技术和加筋土结构设计技术。均质化技术将应用于加筋土，以产生“等效各向异性连续体”。还将考虑另一种方法，将加筋土视为双组分系统（适用于稀疏加筋土）。计划在标准三轴试验装置上对加筋土样品进行试验验证。破坏准则的各向异性、剪胀特性和破坏模式将被研究。

The objectives of this research are to develop a better understanding of reinforced soil at failure; and to develop a new modeling technique of reinforced soil mass and design techniques of reinforced soil structures. Homogenization techniques will be applied to reinforced soil to produce an "equivalent anisotropic continuum." An alternative approach where reinforced soil is considered as a two-component system (applicable to sparsely reinforced soils) will also be considered. Experimental verification on reinforced soil samples in a standard triaxial test apparatus are planned. Anisotropy of failure criteria, dilatancy characteristics, and failure modes will be investigated.
