This paper presents the results of fundamental experiments on the soil improvement method by underground water jet. This new soil improvement method develops with object to increase permeability of soils for underground coffer dam, underground water way and others. The means of this soil improvement is that soils are scoured and disturbed by high velocity water jet under ground, and fine soil particles are removed by water flow which rises to ground surface. Namely the principle of this method belongs to the category of the granular soil stabilization or the mechanical soil stabilization. In this paper, the authors considered the extents of improvement of soils which were scoured and disturbed by underground water jet, the properties of soils (effect of granular soil stabilization, change of permeability, suitability to the conditions of filter, volume change of soils, etc) which were improved, and the quantity of water which was required to improve soils by this new method.
