水闸的波浪要素计算（完整版）实用资料(可以直接使用，可编辑完整版实用资料，欢迎下载）水闸波浪要素计算波浪要素可根据水闸运用条件，计算情况下闸前风向、风速、风区长度、风区内的平均水深等因素计算。波浪压力应根据闸前水深和实际波态进行计算。（1）平原、滨海地区水闸按莆田试验站公式计算和：（1）（2）式中hm——平均波高，m；V0——计算风速，m/s，可采用当地气象台站提供的30年一遇10min平均最大风速；D——风区长度，m，当对岸最远水面距离不超过水闸前沿水面宽度5倍时，可采用对岸至水闸前沿的直线距离；当对岸最远水面距离超过水闸前沿宽度5倍时，可采用水闸前沿水面宽度的5倍；Hm——风区内的平均水深，m，可由沿风向的地形剖面图求得，其计算水位与相应计算情况下的静水位一致；Tm——平均波周期，S。（2）根据水闸级别，由下表查得水闸的设计波列累积频率P（％）值。表1P值表水闸级别123P（％）125（3）累积频率为P（％）的波高hP与平均波高hm的比值可由下表查得，从而计算出hP。表2hp与hm的比值P（%）1251020500.02.422.231.951.711.430.940.12.262.091.871.651.410.960.22.091.961.761.591.370.980.31.931.821.661.521.341.000.41.781.681.561.441.301.010.51.631.561.461.371.251.01（4）按下式计算平均波长Lm值（3）式中H——闸前水深，m。平均波长Lm值也可由下表查得。表3Lm值H(m)Lm（s）234567891012141618201.05.228.6912.0015.2418.4421.6724.7927.9631.1137.4143.7049.9856.2662.542.06.0511.3116.2320.9525.5830.1634.6939.2043.7052.6661.5970.5079.4088.293.06.2212.6818.9624.9330.7236.4142.0347.6153.1664.1975.1786.1297.04107.954.0－13.4120.8627.9534.7741.4448.0154.5160.9673.7786.5099.18111.82124.445.0－13.7622.2030.3138.0945.6653.0860.4167.6882.0896.37110.59124.76138.906.0－13.9323.1332.1940.8749.2757.5065.6173.6289.49105.20120.82136.38151.907.0－－23.7833.6943.2252.4261.4170.2478.9696.19113.23130.15147.00163.798.0－－24.2134.8945.2255.1964.9074.4383.82102.33120.62138.77156.82174.809.0－－24.4935.8446.9457.6568.0578.2488.27108.01127.49146.79165.98185.0910.0－－24.6836.5948.4159.8270.9081.7392.37113.30133.91154.31174.58194.7612.0－－24.8737.6450.7363.4975.8587.9099.73122.89145.64168.13190.44212.6214.0－－－38.2552.4266.4079.9893.20106.14131.42156.18180.61204.82228.8716.0－－－38.6153.6268.7283.4597.78111.78139.09165.76192.02218.02243.8318.0－－－38.8054.4770.5586.35101.75116.79146.03174.53202.55230.25257.7220.0－－－－55.0571.9888.79105.21121.24152.36182.62212.33241.66270.7222.0－－－－55.4473.1090.83108.22125.21158.15190.12221.45252.35282.9524.0－－－－55.7173.9692.53110.85128.75163.47197.10230.00262.42294.4926.0－－－－55.8874.6193.94113.13131.93168.36203.61238.05271.94305.4428.0－－－－－75.1095.10115.
