摘要
通过分析施工洪水过程中的洪峰流量、洪量和历时的不确定性及导流建筑物的水力参数的不确定性,确定施工洪水过程和导流建筑物泄流能力的模拟计算模型。运用Monte-Carlo方法模拟计算施工导流系统渡讯各时段的状态参数,得到上游围堰堰前水位的分布函数,在此基础上确定导流系统的风险。
Based on analying uncertainties of construction diversion system, this paper presents the simula tion model of construction flood and discharge capacity of diversion structure, and the model includes uncertainties such as peak flow, flood volumes, flood duration and hydraulic parameters of discharge constmction. The Monte - Carlo method is applied to simulate the state parameters of the construction diversion system in every period of time. As a result, a random distribution function of the upstream water level is obtained, then the risk of the diversion system is determined.
