In the case of construction on soft ground, some special type of foundation must be used. So for the end bearing pile foundation has been mostly used.However, in the case of such a foundation, some problems have also been pointed out like negative skin friction of the piles and differential settlement.In this research, instead of the end bearing pile, the following foundation methods have been theoretically and experimentally investigated : (1) a friction pile foundation method which is a method of supporting a load by mainly frictional strength between pilesurface and cohesive soil, (2) a stabilized box foundation method which is a method of making an inverted box by constructing in situ, overlapping columns of stabilized soil along the periphery of the box and making a top slab of stabilized soil so that the structure is supported on the box, (3) a light weight foundation method which is a method of making the weigth of foundation itself light by mixing clay with expanded Poly-Styrol and quick lime.According to the results, these three kinds of foundation methods are found to be fairly useful for supporting structures in soft Ariake clay.These methods also reduce the total and differential settlement while the bearing capacity is increased.

如果在柔软的地面建造，则必须使用一些特殊类型的基础。因此，对于末端轴承桩的基础，几乎是在这样的基础的情况下，也已经指出了一些问题，例如堆积和差分定居点的负面皮肤摩擦，而不是最终轴承堆，以下基础方法是在理论上和实验上进行了研究的基础方法： a stabilized box foundation method which is a method of making an inverted box by constructing in situ, overlapping columns of stabilized soil along the periphery of the box and making a top slab of stabilized soil so that the structure is supported on the box, (3) a light weight foundation method which is a method of making the weigth of foundation itself light by mixing clay with expanded Poly-Styrol and quick lime.According to the results, these three kinds of发现基础方法对于支持软芳基粘土中的结构非常有用。这些方法还降低了轴承能力，同时降低了差异和差异。
