CONSTRUCTION METHOD OF HARBOR STRUCTURE
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
【課題】港湾構造物の工事関係者が、中詰施工時の港湾構造物の安定性が確保されているか否かを設計時に知ることができる港湾構造物の構築手段を提供する。【解決手段】中詰施工を要する港湾構造物の底面積、中詰材の物性、中詰材の投入速度、港湾構造物の外側における水位に基づき、中詰材が含む粒子の粒径区分毎の沈降速度、粒子の水中浮遊量、粒子の堆積高、港湾構造物内の泥水密度、港湾構造物の内側下端部における水圧を、中詰材の投入開始から１０分後、２０分後、といった複数の算出時点の各々に関し算出し、それらの数値を用いて、中詰施工時の港湾構造物の内外水位差を時系列で算出する。港湾構造物の工事関係者は、算出した内外水位差を閾値と比較することにより中詰施工時の港湾構造物の安定性を評価し、安定性が確保されると評価された条件の下で中詰施工を行う。【選択図】図２
