Elasto-plastic description of mechanical behavior for unusual soils based on soil skeleton structure concept

异常土是设计施工中难以处理的问题。此外，异常地基往往会造成大面积的地基破坏，这是正常施工管理无法预测的。近年来，许多重要的基础设施都是在填填异常土和中间土的人工填海基础上建设的。因此，正确认识异常土的力学特性，对合理设计施工具有重要意义。在本研究中，为了理解和解释基于土壤骨架结构概念的力学行为，利用不同寻常的土壤和中间土壤进行了各种实验室实验。

Unusual soil l is the soil which became the problem that the handling is difficult in design construction. Moreover, unusual soil foundation often causes extensive ground damage which cannot predict by the normal construction management. Recent years, many important infrastructures are constructed on an artificial reclaimed foundation filled up with unusual soils and intermediate soils. Therefore, it is very important to comprehend the mechanical behavior of unusual soils properly and make use for adequately design construction. In this research, various laboratory experiments were conducted using unusual soils and intermediate soils for the purpose of understanding and interpreting its mechanical behavior based on a soil skeleton structure concept.
