The frist step is selecting any gage that building in the river basin as rainfall center, and adding the nearest rain gauge step by step to calculate the point and areal rainfall for different size of area. Using different gage that in the river basin as rainfall center can get the result of different case.

研究中，先以某个雨量站当成点降雨中心，并逐次纳入邻近雨量站，即可分别得到不同面积下之点降雨及区域面积降雨，依序置换不同雨量站为中心进行相同之分析，即可得到所有可能组合案例之分析结果，利用Gamma分布可进一步推求不同重现期距之点降雨及区域面积雨量，即可建立研究区域之ARF。

The advantages and limitations of every kind of methods for calculating the failure probability is reviewed. The frist order reliability method, the second order reliability method and many kinds of boundary method have achieved remarkable success and formed nature fields of reliability. However, the precision of these methods decrease as the increase of complexity of problem. The numrical methods are versatile, except numerical intergration is only adaptable to special problems which have small number variables and regular intergral domain. Particularly, the advanced variance reduction techniques own the following character: high precision and a small amount computation. But some questions remain to study in the future because only an initial work about these techniqes is developed.

全面评述了计算失效概率各种方法的优点和局限性，其中经典的解析法包括一次可靠性方法、二次可靠性方法、一阶边界法、Vanmarcke上边界、PENT上边界和Ditlevsen二阶窄边界法，这些方法对于多设计点、变量较多且相关、密度函数不是正态以及极限状态方程较复杂的情况，其计算精度较差；而已有的数值方法却是具有较好的通用性，其中除数值积分法只对变量较少、积分域较规则的特殊问题适用外，各种数值模拟方法均具有较广的适应性，特别是各种改进的方差减小技术，精度高、计算量小，但由于其处在研究的初级阶段，还有许多问题有待于解决。
