Provided is a hat-type steel sheet pile of which the economic feasibility, the constructability, and the integrity are optimized. The hat-type steel sheet pile according to the present invention comprises: an upper flange part; web parts consecutively formed at both ends of the upper flange part; and lower flange parts formed at the respective end portions of a pair of the web parts. When a steel sheet pile wall is completed by the hat-type steel sheet pile, relations between a geometric second moment per meter (I cm^4/m) in the width of the wall, a weight (W kg/m^2) per the area of unit wall, and a penetration resistance (R) and a web angle (θ°) are determined to satisfy one of a formula group (A) or a formula group (B) below. The formula group (A) includes: (W/I) * R <= 0.04; 2.65 * (10^-4) * (I + 22) <=θ<= 2.80 * (10^-4) * (I + 48), wherein 20000 <= I < 80000; and 2.65 * (10^-4) * (I+22) <=θ<= 70, wherein 80000 <= I < 180000, and the formula group (B) includes: 0.004 < (W/I) * R <= 0.0075; 2.80 * (10^-4) * (I + 44.6) <θ<= 80, wherein 20000 <= I < 80000; and 67 <θ<= 80, wherein 80000 <= I < 200000. |
