（3）其它历时设计点暴雨量计算。将工程集水区中心的24h设计点暴雨量代入下列公式计算其它历时的设计点暴雨量：
历时（t）为2、3??5h：Htp?H24p?4?N3p?N2pN2p统计参数 Ht（mm） Htp（mm） P= % Cvt Cst 3.5Cv1 3.5Cv6 3.5Cv24 P= % P= % ?6?t
历时（t）为7、8??23h：Htp?H24p?24按公式计算：
N2p?1.285lgH6pH1p?N3p?tN3p
式中：N2p、N3p为设计暴雨的递增指数值，可由1、6、24h设计点暴雨量
N3p?1.661lgH24pH6p
2．1至24小时设计面雨量计算
河流在工程断面发生的洪水系由断面以上集水区的（面）雨量所形成，点设计暴雨量必须经过点面关系化算成面设计暴雨量。由附图7《暴雨区划图》划定工程集水区所在暴雨分区，查《云南省分区综合时～面～?、见表（7），?关系表》得到工程集水面积（F）的不同历时（t）的点面雨量折算系数?Ft，则1至24h设计面雨量HFtp??Ft?H点tp。
在面雨量计算时经常会碰到的问题及其一般处理有：（1）工程集水区在两暴雨分区的交界处，可取两区的平均的?值，在经分析后亦可取其中暴雨相似区的
?值；（2）工程集水区面积（F）不为表列数值，以其左右相邻F的?进行线性
插值；（3）查算不为表列历时t的?Ft，是采用上下相邻?Ft进行线性插值。
须予说明的是，只有当工程集水区的分水线与暴雨的等值线相重合时，应用

点面折算系数将点雨量化算成面暴雨量才是合适的，但实际上是不相重合，理应将点面折算系数修正为较小数值，实用时为安全起见可不修正。
