:Abstract

Rock material are from best natural good material that use in road body structure,breakwaters,stone dams and other engineering purposes .breakwaters are one of important engineering structure that made by this material.therefore always recognition of their behavior in related with water flow and degeneration effects their environment over them was to bring consideration of designer engineer.rock durability and its strength in contact with destructive and invader dominant factors on sea environments are from important characteristic that should be exist in material used in made of sea foundations and breakwater , in particular. Breakwater Stability to depend on defferent factors such as seeming shape of protector layer rocks and their density,made method of bed layers and breakwater layers,geometry condition of foundation,dip angle,coronate height etc.for examination of igneous rocks function used in breakwater,first,select some breakwater that builded in country south coasts,and sampling from breakwater rocks and mines of this rocks.Laboratory studies that used for this rocks include determine of physical ,mechanical,chemical and mineralogical properties of this rocks and soundness and durability tests.object of this study is recognition of material behavior used in sea foundation and their durability ,for use best material in made of this foundation.

Key words:Igneous rocks,breakwater,durability,physical and mechanical tests,Persian gulf coasts.
