When soil is frozen, its compressive strength below -30°C is nearly equal to that of concrete (200kgf/cm2). The tensile strength of the frozen soil is 1/10 of compressive strength as strong as that of concrete. Therefore it is made clear that“Reinforced Frozen Soil”(the frozen soil is reinforced by steel) functions the same as reinforced concrete do. As the result of fundamental experiment, the three fundamental conditions acted as compound structure are gratified in reinforced frozen soil as well as in reinforced concrete. (1) The cohesive strength between frozen soil and steel is beyond between concrete and steel. (2) The coefficient of linear expansion in reinforced frozen soil is nearly equal in R. C.. (3) Steel doesn't rust in fozen soil.
