Abstract: To provide construction means of a harbor structure in which construction-related people of a harbor structure can know whether stability of the harbor structure in filling construction is secured at a time of design.SOLUTION: A sedimentation velocity of particles contained in a filling material for each particle size section, an underwater floating amount of particles, a deposition height of particles, muddy water density in a harbor structure, and water pressure at an inner side lower end portion of the harbor structure are calculated for each of a plurality of calculation points such as ten and twenty minutes after start of feeding of the filling material, based on a bottom area of the harbor structure requiring filling construction, physical properties of the filling material, feeding speed of the filling material, and water level at an outside of the harbor structure. Using those numerical values, an inside-outside water level difference of the harbor structure in the filling construction is calculated in time series. Construction-related people of the harbor structure estimate stability of the harbor structure in the filling construction by comparing the calculated inside-outside water level difference with a threshold value, and perform the filling construction under a condition where it is estimated that stability is secured.SELECTED DRAWING: Figure 2
