Weir dam leakage control structure based on calculus thought and dangerous case characteristics and optimization method of weir dam leakage control structure based on calculus thought and dangerous case characteristics

The invention provides a dam leakage control structure based on calculus thought and dangerous case characteristics and an optimization method thereof, the leakage control structure comprises a drainage tank structure suitable for a soil dam or a rock dam capable of being excavated in the whole line and a pile driving structure suitable for the rock dam difficult to excavate in the whole line, and when the number of bealocks of the dam is 1, the pile driving structure is suitable for the rock dam. The bealocks serve as inlet positions of the draining grooves, when the number n of the bealocks is larger than or equal to 2, the draining grooves are obliquely excavated from the position close to the dam middle to the tail end of the dam top face adjacent to the river bank on the single side, and the drained water flow is perpendicular to and scours the river channel concave bank as much as possible through the inertia and centrifugal force effects generated when dam breaking water flow main flow is drained; the
