K3 - geospatial factor of 1.3; W0 - basic air pressure value (W0 = V2/1.6) V - 15 m/s wind speed; W = 1.3 · 1.1.3 · 15/1.6 = 237.6 Pa (the parameters are checked in appendix) Wave force, flood impact, tidal force, etc. P is equal to K times A dot gamma V2 over 2 grams. P - water pressure, kN, the distribution of water pressure is assumed to be an inverted triangle, and its net force is one third below the water level. K - the coefficient on the shape of the blocked water section, taking 1.33; A - block water area (m2), lower calculation to general erosion line (53 # pier in calculation of general erosion line, to 1.58 m) the largest block water area of A = 0.53 x (7.35 + 1.58) = 4.73 ㎡ Gamma-water, take 10kN/m3 G -- the acceleration of gravity is 9.8 m/s2 V - velocity of water (m/s), considering the addition of wave and flood to 3.0 m/s P is equal to
