In order to study the foundation settlement and the bearing capacity of the ground reinforced by slender steel pipes, laboratory and in-situ vertical loading tests were conducted. The result can be summarized as follows. The reinforcement of ground by pipes decreases the settlement of foundation and increases the bearing capacity of the ground. These effects are more remarkable when longer pipes are used, and when soil layer near the pipes end are harder than the surface layer. If pipes having the ultimate bearing capacity of 1.5tf or more per pipe are installed such that there is two pipes in every area interval of 45×60cm, the reinforced ground having long term allowable bearing capacity of 5tf/m^2 or higher can be obtained. However, the long term allowable bearing capacity of a reinforced ground can't be obtained by simply summing up the long term allowable bearing capacity of the pipes and of the unreinforced ground.
