摘要

Stone-much had been wated in may quarries in Japan after rubbles or rock(stone) materials were produced. However, the huge amount of stone-much that remained in quarried is recently spotlighted ad construction material especially for port and harbor structures because of its low cost perofrmance and environmental preservation. The authors made field investigations on main quarries in Tohoku district (northern area of Honshu island) to study the production process and piled condition of the stone-much. A series of large scale triaxial compression tests and some physical tests were carried out on stone-much samples collected from typical quarries taking into account its use as construction material for the port and harbor structures, for instance as mound foundation of breakwater or as backfill behind revetment. It is found from these studies that the geotechnical characteristics of the stone-much are related to the production process of rubbles(rock materials), its geological background and the degree of weathering of rock mass. It is also proved that the strength characteristics are strongly related to uniformity coefficient, particle breakage under confining pressure and dilatancy at failure. It is concluded in this paper that if the stone-much is placed on appropriate part according to its characteristics, it can be used effectively as construction materials for the port and harbor structures.
