This study examines effective ground improvement of clay soils. As simplifying the cost as the integral of the material strength over the volume, strength distribution optimization is formulated to realize the desired bearing capacity. Numerical experiments indicate that effective ground improvement can be expected if the strength distribution enables slip lines to extend both vertically downward and laterally across the ground.
