PURPOSE:To reduce the weight of a structure by raising the sliding resistance of a superstructure to be placed on the improved ground by a method in which a solidifying agent is charged slantly into soft ground and mixed the soil with stirring in such a way as to harden and improve the ground to form skew improved soil pillars or walls. CONSTITUTION:Unimproved ground in the seabed is removed to some extent, and improvement in the vertical direction is made on the ground in the same way as in the usual method to form a vertically improved ground 2. Furthermore, improvement in the slant direction is made on the ground to form a slantly improved ground 3. When a heavy structure 1 is constructed on the improved ground, the horizontal force acting on the structure 1 is transmitted to the slantly improved ground 3 through oblique planes 4 formed by slantly cutting the bottom of the structure 1. |
