<P>PROBLEM TO BE SOLVED: To provide a hat steel sheet pile for which economical efficiency, workability and soundness are all optimized. <P>SOLUTION: The relation of a geometrical moment of inertia I(cm<SP POS="POST">4</SP>/m) per meter of a wall width when forming a steel sheet pile wall, weight W(kg/m<SP POS="POST">2</SP>) per unit wall area, penetration resistance R and a web angle θ(°) satisfies one of following formula groups (A) and (B). The formula group (A): (W/I)×R≤0.004, and 2.65×10<SP POS="POST">-4</SP>×I+22≤θ≤2.80×10<SP POS="POST">-4</SP>×I+48(20,000≤I<80,000), 2.65×10<SP POS="POST">-4</SP>×I+22≤θ≤70(80,000≤I<180,000). The formula group (B): 0.004<(W/I)×R≤0.0075 and, 2.80×10<SP POS="POST">-4</SP>×I+44.6<θ≤80(20,000≤I<80,000), 67<θ≤80(80,000≤I<200,000). <P>COPYRIGHT: (C)2012,JPO&INPIT |
