Abstract

An overview about the behaviour of two soft soils (Kaolin Silt and Lower Rhine Clay) under monotonic as well as cyclic loading is presented. Thereby it is shown that especially Kaolin possesses an inherent anisotropy, which can be described by a transformation and through scaling of the tangential stiffness tensor. The AVISA model is enhanced and shows accurate reproduction of the behaviour of these soft soils under cyclic as well as monotonic loading. Through a third strain mechanism the behaviour of both plastic and non-plastic soft soils can be described very well.

粉土和粘土的循环和单调响应：实验分析和本构建模

摘要

概述了两种软土（高岭土和下莱茵粘土）在单调和循环载荷下的行为。由此表明，特别是高岭土具有固有的各向异性，这可以通过切向刚度张量的变换和缩放来描述。AVISA 模型得到增强，可以准确再现这些软土在循环和单调载荷下的行为。通过第三种应变机制，可以很好地描述塑性和非塑性软土的行为。
