The present invention relates to a model caisson anchor for measuring soil resistances separately, wherein the model caisson anchor allows an optimal load point to be easily found by separately measuring the soil resistances which are resistances applied to the inside and the outside of a caisson anchor used as the foundation of a floating marine structure. The model caisson anchor of the present invention comprises: a main rod of which one end is applied with a load; a hollow tube-shaped outer cylinder coupled to the other end of the main rod and having closed one end; a hollow tube-shaped inner cylinder coupled to the outer cylinder by a fixed rod vertically protruding, separately housed inside the outer cylinder, and having closed one end; an outer resistance measuring part mounted on the main rod and measuring the soil resistance applied to the outer cylinder; and an inner resistance measuring part mounted on the fixed rod and measuring the soil resistance applied to the inner cylinder. According to the present invention, the model caisson anchor for measuring the soil resistances separately is capable of separately measuring the resistances applied to the inside and the outside of the caisson anchor according to the structure of the outer and the inner cylinder which are separately placed. Therefore, the position of the optimal load point is easily identified by a moment and a horizontal resistance. In addition, reaction forces with three degrees of freedom (horizontality, verticality, and moment) are measured when applied to the embedded caisson anchor moving horizontally, and a friction coefficient, a bearing capacity coefficient, and a failure envelope are conveniently defined when horizontal, vertical, and diagonal cyclic loads are applied. |
