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.

异常土l是指在设计施工中成为处理困难的问题的土。此外，异常的土基常常会造成大范围的地面破坏，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人工开垦的地基上建造的，其中填满了异常土和中间土。因此，正确理解异常土的力学行为并用于充分的设计施工非常重要。在这项研究中，使用异常土壤和中间土壤进行了各种实验室实验，目的是基于土壤骨架结构概念来理解和解释其力学行为。
