Abstract
This paper presents a method of utilizing 3D data for wave-dissipating works aiming for more efficient and advanced design and construction. In the design phase, by calculating the required quantity of the wave-dissipating blocks from the volume directly obtained from the 3D data, the time required for the work is remarkably shortened. It is also possible to calculate required quantity of the blocks considering the engagement with the existing blocks by utilizing the 3D printer. In the construction phase, by using an installation system which guides the position of the blocks based on the 3D data created beforehand, the operation time of the crane is shortened. In addition, a method to optimally arrange the block shape 3D data into the point cloud is developed. The method was verified that it can create a 3D model including the position information of individual blocks in a short time with high accuracy. By utilizing this method, further improvement in efficiency of design and construction of wave-dissipating works can be expected.
