Abstract

PURPOSE: To increase the accelerating effect of consolidtion of soft ground by a method in which the property of water contained in the soft ground is improved so as to enable the water to pass through the ground, and then a consolidating load is applied on the ground.
CONSTITUTION: A liquid which does not solidify during the consolidation period, having a surface tension smaller than that of water contained in soft ground and consisting of molecules with smaller polarity than that of the water, or having a smaller surface tension than that of the main constituent mineral of the ground and consisting of molecules with smaller polarity than that of the water, or having property by which the surface tension of the water is made smaller than the limiting surface tension of the main constituent mineral of the ground and consisting of a surfactant capable of reducing the polarity of the water, is injected into the soft ground in order to improve the property of the water in the ground, and then a consolidating load is applied on the ground.
