Abstract
The construction control of the structures has been recently recognized as one of the most important matters in a series of design procedures. An embankment on a soft ground is usually constructed by the smaller safety factor compared to other structures, because the change of design under construction is comparatively easy in the earth work. This makes it especially important in the embankment construction to control safely and quickly by using the information obtained from the practically possible measurements. The present paper describes the study on the method in which the degree of safety at the present situation is ascertained and the successive failure is predicted by observing the vertical settlement at the central place just under an embankment and the horizontal displacement near the toe of the slope. Many observed and numerical examples are shown, and on the basis of them, the diagram for practical use of the construction control is proposed.
