华北水利水电大学⑵波浪爬高波浪爬高按下式计算式中：RP—累积频率为P的波浪爬高，m；KΔ—坡面系数；KV—风速系数；KP—爬高累积频率换算系数；m—斜坡坡率。表5.7波浪爬高要素参数表堤防H（m）L（m）KΔ（m）KVKPmRP左右堤0.256.230.911.8420.92(3)风雍高度式中：K——综合摩阻系数，取3.6×10-6；V——设计风速，取汛期多年平均最大风速的1.5倍，汛期多年平均最大风速为15.2m/s，则V=22.8m/s；F——吹程，取上口宽；D——平均水深；β——风向与垂直堤轴线的法线的夹角，β=0；经计算，e=2.12×10-4m,因为风雍高度值很小，可以忽略不计。(4)超高堤顶超高按下式计算：y=R+e+A式中：y—堤顶超高，m；R—波浪爬高，m；e—风雍高度，m；A—安全加高，m。左、右堤（四级）均取A=0.6m，见表5-8。表5-8堤防工程顶部安全加高(m)防浪条件堤防级别12345不允许越浪1.00.80.70.60.5允许越浪0.50.40.40.30.3经计算，左右堤超高为y=R+e+A=0.92+0.6m=1.52m。堤顶高程是设计水位与堤顶超高两者之和，计算成果见表5-5表5-5黄龙渠水力要素设计成果桩号设计河底5年除涝水位20年除涝水位堤顶高程4+40064.0665.5966.0667.584+60063.7065.2365.7067.224+80063.3364.8665.3366.855+062.9764.5064.9766.495+20062.6064.1364.6166.135+40062.2463.7764.2765.7945+60061.8763.4063.9665.4815+80061.5163.0563.7165.236+061.1462.9163.5265.0356+20061.0362.8363.4064.9216+40060.9362.7363.3064.8216+60060.8262.6263.1964.7116+80060.7262.5263.0964.6117+060.6162.4162.9864.5017+20060.5162.3162.8864.4017+40060.4062.2062.7764.2917+60060.2962.0962.6664.1817+80060.1961.9962.5664.0818+060.0861.8862.4563.9718+20059.9861.7862.3563.8718+40059.8761.6762.2463.7618+60059.7761.5762.1463.6618+80059.6661.4662.0363.5519+059.5561.3561.9263.4419+20059.4561.2561.8263.3419+40059.3461.1461.7163.2319+60059.2461.0461.6163.1319+80059.1360.9361.5063.02110+059.0260.8261.3962.91110+20058.9260.7261.2962.81110+40058.8160.6161.1862.70110+60058.7160.5161.0862.60110+80058.6060.4060.9762.49111+058.5060.3060.8762.39111+20058.3960.1960.7662.28111+40058.2860.0860.6562.17111+60058.1859.9860.5562.07111+80058.0759.8760.4461.96112+057.9759.7760.3461.86112+20057.8659.6660.2361.75112+40057.7659.5660.1361.65112+60057.6559.4560.0261.54212+80057.5459.3459.9161.43413+057.4459.2459.8261.33713+20057.3359.1359.7161.22913+40057.2359.0359.6161.13313+60057.1258.9259.5161.02813+80057.0158.8159.4160.92914+056.9158.7159.3160.82814+20056.8058.6059.2060.72314+40056.7058.5059.1160.63114+60056.5958.3959.0160.5314+80056.4958.2958.9260.44115+056.3858.1858.8260.34315+20056.2758.0758.7360.24815+40056.1757.9858.6460.16415+60056.0657.8758.5560.07415+80055.9657.7858.4859.99716+055.8557.6758.3959.91316+20055.7557.5858.3259.84416+40055.6457.4858.2559.76716+60055.5357.3958.1859.69516+80055.4357.3058.1259.63617+055.3257.2158.0559.57217+20055.2257.1458.0059.52217+40055.1157.0557.9559.46617+60055.0156.9957.9059.42417+80054.9056.9157.8659.37618+054.7956.8557.8159.33318+20054.6956.7957.7859.30318+40054.5856.7457.7559.26518+60054.4856.7057.7259.24218+80054.3756.6557.6959.21119+054.2656.6157.6659.18219+20054.1656.5857.6559.16619+40054.0556.5557.6259.14319+60053.9556.5357.6159.13319+80053.8456.5057.5959.11320+053.7456.4957.5859.10420+20053.6356.4757.5759.08720+40053.5256.4557.5559.07120+60053.4256.4457.5559.06820+80053.3156.4357.5459.05521+053.2156.4257.5359.05221+20053.1056.4157.5259.04121+40053.0056.4157.5259.0421+60056.3156.4057.5159.02921+80056.2456.3157.4058.92322+056.1556.2357.3358.84722+20056.0656.1557.2458.76122+40055.9756.0657.1658.67622+60055.9055.9757.0758.59122+80055.8155.9057.0058.51723+055.7355.8156.9158.43423+20055.6455.7256.8358.35123+40055.5755.6456.7558.26923+60055.4855.5656.6858.19823+80055.4055.4756.6058.11724+055.3155.3956.5258.03624+20055.2455.3156.4457.95624+40055.1655.2356.3757.88724+60055.0855.1556.2957.80824+80055.0055.0756.2157.7325+054.9354.9456.1357.65325+20054.8554.8656.0757.58825+40054.7754.7855.9957.51325+60054.6954.6955.9257.43925+80054.6354.6155.8557.36626+054.5654.5355.7857.30426+20054.4854.4555.7157.23326+40054.4154.3755.6557.16526+60054.3554.2955.5857.09826+80054.2854.2255.5257.04227+054.2254.1455.4656.97727+20054.1554.0655.3956.91327+40054.1053.9955.3356.85127+60054.0453.9255.2856.827+80053.9853.8555.2256.74128+053.9353.7755.1656.68328+20053.8853.7055.1156.62628+40053.8153.6455.0656.58228+60056.3153.5855.0156.52928+80049.7453.7254.9356.44829+049.6553.6554.8656.3829+20049.5753.6054.8156.32529+40049.4853.5454.7456.26229+60049.3953.4854.6856.20129+80049.3053.4254.6256.14230+049.2253.3754.5756.09430+20049.1353.3254.5256.03630+40
