Abstract
The North Breakwater of Otaru Port which consists of mound and superstructure, was constructed by the sloping-blocks were settled down by an overhanging crane which is well known as Taitan. To ensure the stability of blocks, it is necessary to bond together every block of each separate section.
This paper addresses the way and effects of bonding blocks in the North Breakwater of Otaru Port. Detailed investigations have been made on “the Report of Otaru Port Construction Works” written by Dr. Isami Hiroi who focused on researches of sloping-blocks and infrastructure works of the North Breakwater.
